Bitcoin Forum

Do you ppl have some kinda minimum limit for buying bitcoins? I mean for currency.

Well, you can "buy" a few satoshi from a faucet ;D

Well I guess the minimum in my country is one cent of vision, as that's the lowest possible denomination of the Australian dollar. Since that is also the minimum that can be transacted, I guess that's the minimum amount of bitcoin you can buy.

Maybe in another country you can buy a few satoshi, due to the low denominations. But none will want to sell a few satoshi xD

The exchanges can have limits for low orders, but if they didn't have it you can't spend less than 1 cent 0.01 of fiat money.

Hmm, not that i am aware of. The only limit should be the transaction fee to sustain the network.

Or in most cases the limit an exchange uses to buy or sell bitcoin.

There's isn't such a thing as limit when you buy from another person, in person so no worries there as long as it's more than the transaction fee which is so little that couldn't be called a limit but on the other hand like what Raimonn said, there are some limit if you use an exchange to buy BTCitcoins

There is no such limit if you buy in person from someone, You can buy even few satoshi's. Few Exchanges have a minimum limit and few transactions have a fixed fee, In that case buying like 0.1 BTC will do.

if you mean the limit on exchange, there are none unless you have not verify your identity

if you mean what we can afford to lose, then i think basically everyone should have a limit

at theccurent rate 0.5-1 btc at max, per month would suffice

I never heard of anyone having a limit on buying bitcoins

I think that as long as they make some profits on it they can buy as many bitcoins as they want

As in investing/selling/trading/buying

Depends on where and how you buy. I usually buy on the Dutch website Bitonic where one can buy Bitcoin with fiat directly from a bank account, minimum there is 2,50 euro worth of Bitcoin. But yeah, in many cases the 'bottom' is indeed 1 satoshi.

As bitcoin we can even send 1 satoshi payment so when price will be in moon we can buy minimum 1 satoshi but in fiat it depends on currency like 1 cent for USD.

If I understood you right , you want to know if we have some limits that we shouldn't pass while buying bitcoin ?
I personally don't buy them and all of them are profit from different things (services , sig campaigns , etc ...) so I'd say Ihave no limit , the more the better because if Bitcoin become used by more and more people over the years , it will worth more and owning at least 1 BTC at that time will be more then good .

if you buy in the exchanger/trade are usually minimal to buy around 0.01BTC, but if you buy from your friend probably minimal around 0.001BTC :)

But you can make that trade happen in exchanges. I bet you could even buy a single satoshi if you're that cheap.

The minimum limit for buying bitcoin is the one you set for yourself.

it kinda depends on the exchange. but the lowest amount of bitcoins i have bought is 0.001btc. and i bought it without problems on btc-e.

Every exchange should have a TOS (terms of service) where they clarify the minimum transaction order. I am not sure there is a website where you can compare it, but 0.01 seems to be a logical amount to exchange.

Of course in person no limit exists. If you are buying from the exchanges, some limit has to exist. If you want to buy to low of amount, you need to think of the wiring money costs, credit card costs, etc.

Also exchange operating costs are important. Exchanges don't want that you waste their resources with low orders. Of course, these low orders will be very rare.

Don't forget every exchange has a withdrawal fee. For kraken f.e. it is 0.005 BTC (yeah a lot) so it means you have to buy min. 0.005.

That's correct, so the minimum limit depends on

1 transaction fee of the exchange (normally around 0.2 %)
2 withdrawal fee
3 network fee

It depends on the exchange there is a practical limit when purchasing Bitcoins, buying a $1 but paying a $5 dollar fee to get that dollar isn't very economical.
Some exchanges do have stated minimum deposits depending on the method you use.
Example Direct Withdrawals, In Person Bill Payments, Online through services like Quickbt, Wire transfer etc.

I usually buy %10 of my monthly wage but sometimes more. I'd never measure the minimum though. Even I have 1$ I can buy BTC.

100$ seems to work and makes it enough so everyone cares - I found trying to get like 30-50 people cant be bothered so u get hackers and kids

There is no minimum limit to buy bitcoin. If you have spare money of $100, then it is a good figure to buy some bitcoins.

The minimum varies between each country I would say.
In some, people won't move for less than 100$, and in others 1$ might be enough.

For me it is around $200. If I agree to buy I tend to buy at least this much.
Some people are skeptical so they think they are wasting their hard earned money. So I suggest them to buy for like $20-$50.

If you are to buy btcs you will limit yourself from buying more else you will end up losing as the value isn't stable.
Let say price today is $400, you will lose tons of cash when you discover that after a month BTC's value turn $300. so if you bought 25btc during the tie when its value was $400, you lose money. you will have to wait till it goes up before you gain.

That is about the same strategy as me :) Doing it since this year, so avarage buy price has been quite good so far!

Mininum you can buy probably depends on what you have to spend.

i think every exchange have minimum limit,and its different evry exchange.

The answer of this question is to easy to be given. The limits are according to the desire or the will of the owner/manager/CEO/managing director or everyone who have to do with such kind of job in that subject where can be bought bitcoin. Don't exist any fixed limit. In every subject in which can be bought bitcoin exist different limits. If you want to know the limit ask before and for sure you will have your answer. There where you want to buy bitcoin.

You could buy a satoshi, but I really don't think anyone will sell it to you. They'd also require you to pay for the tx fee, which is twenty thousandfold more than what you want to buy, so I don't see why you would want to buy so little.

One of the best things about Bitcoin is that you don't need thousands of dollars before you can invest in it.

this is very true. We were thinking about giving the little ones in our family $20 btc so they could save it
and maybe get more into it.

yes I am curious too.
if the rate of PTC is down i want to buy BTC, but if we could buy for example 0.5 BTC?

I don't think there is any base-line minimum limit for how much Bitcoin you can buy, I would say that it's anything you can purchase for $0.01 in an exchange. Alternatively, however, you can "buy" about 5k Satoshis from faucets, in exchange for a few minutes of your time. You can even get as little as 1k from some faucets as a minimum for one withdrawal.

I personally have no limit, I just invest what I have available.

My experiences from 3 exchanges is that it's impossible to buy less than 0.1 BTC. And it's logical. Nobody wants to bother with less than that. On some exchanges you can have a peak of past exchanges, and you won't see anything below that. Most transactions are over one BTC.

That depends totally by exchanges (owners of exchanges) and the time in which is wanted to be bought bitcoin. Or better mainly from the price of bitcoin. Because even the owners/managers of exchanges have their logic in the creation of their policies regarding such things. If the price of bitcoin is high the amount is little. More go high the price of bitcoin more little became the minimum allowed to buy/sell/change it. And the same logic if the price decrease. But in the opposite direction.

I don't think that's the case... The minimum is probably like 1 satoshi or something, on an exchange.

It all depends on your seller/exchange.

If you buy 1 satoshi, it will not be cost effective if you want to transfer to your own account. I think 0.1 bitcoin or higher is OK.

I don't think you'll be able to buy for 1c, due to the fees that are taken by the exchanges. I think it's more 3c or 4c, but I may be wrong.

I wouldn't recommend anyone buying small amounts on a regular basis, IF the transactions fees are high.

I guess every bitcoin exchanger or seller has its own limits for minimum purchases bitcoin, maybe that range from 0005 until 0:01 BTC for a purchase with a minimum purchase

What do you consider to be a small amount?

Here are some of the fees that exchange charge to withdraw BTC.

Btc-e : 0.001 BTC
Kraken : 0.0005 BTC
Bitfinex : Free
Bitstamp : Free

Wow i thought kraken was expensive but btc-e is even more expensive.

Bittrex and C-Cex charges 0.0002 BTC, (to complete your list).

I think there is a limit for buying bitcoin and if you buy below 10.000 satoshi usually they wont sell for you and then if you buy too little you also need to pay transaction fee..so you will lost more money

Here in Belgium I can buy the equivalent of 1 euro in Bitcoin through a service called bitonic (based in The Netherlands).
You can pay with online banking, which is pretty handy for me personally..

I've noticed they have pretty high fees lately, so might still change services in the future.

In my opinion, there's is no minimum limit for buying BTC at all. However you should buy at least 0.001 because that's the least amount that the node accepts to process it ;D (sent with electrum, fee around 0.00015, inputs < 4) well that's the lowest. Anyway I suggest buying at least a dollar or two ;D

I guess it was around 0.1 BTC, or they also sell the dollar, for example, like if you buy a $ 5 you will be provided 0:01 BTC, I guess that's how they sell dollars in order for them to benefit

In my opinion, there's is no minimum limit for buying BTC . you  buy at least 0.001 because that's the least amount . Anyway I suggest buying at least a dollar or two Grin

There is no minimum limit. Its based on traders, some used to sell only higher value of bitcoins. Better to get the least by joining signature campaigns.
While you go for a minimum trade they will have a very minimal transaction charge, this can be eliminated if you earn your own bitcoin.

Just to add to this list,  Yobit is 0.0002 btc.  I don't find that too bad.  I don't remember exactly but I think Cryptsy was more than that, R.I.P.

i think if you buy in someone people not in exchanger. You can buy any bitcoin, which you want. without any limitation of purchase

There is no limit for buying bitcoin or other currencies. In the Poloniex, you can spend 0.0001 bitcoin to buy other coins.

Isn't it more convenient to buy small amounts of BTC right here, on this forum? I have never done it myself but I thought those kind of deals have been made here.

The minimum limit, would always be higher than whatever fee any of these services charge for you to acquire those Bitcoins. Nobody would buy $2 worth of Bitcoins for instance, if it cost you $3 in fees

to acquire it. That said.. if you knew the $2 worth of Bitcoin will double or triple in value, you might be motivated to pay that fee, but it would be stupid.. because nobody has any guarantees for what

the price will be in the future other than speculation.  ::)

actually i don't have minimum limit for buying bitcoin because it all depend on my limit budget
and honestly i didn't ever buy huge amount of bitcoins because i don't have enough money to do so

There is no minimum limit to buy, most exchanges will provide from few dollars itself. Only the transaction fee depends. So to avoid very minimal buying its better to earn through different ways possible.

I have minimum limit for buying bitcoins. It's 0.2 bitcoins per week. Because i am a gambler so everyweek i need to buy 0.2 bitcoins if i lose all my bankroll for gambling.

So you never buy bitcoin lower than 0.2 ever? It is around  $80 , you spend it every week just for gamble? Quiet high amount for people with $400 wage per month like me.

I never limit to buy bitcoin, and what for we limit minimum to buy bitcoin? It will not take effect to anything right? The question a little bit strange.

Canada:

Due to the low price of the current Canadian Dollars the minimum here you can buy in bitcoins is 0.0002BTC, it's pretty much impossible to just get a few Satoshis. Why? Because Bitcoins are hard to get in Canada, you must have a Credit Card if you want to buy them online, Visa/Mastercard. Even then it's hard to find somewhere to buy them because most of the websites require Identity & Address verification, wich are hard to give from here, especially in Québec(Canada).

Unfortunately that is where I live, but fortunately it makes me one of the only buyer/seller from Canada, Québec. Trading is pretty much what I do all day here, it gives me the opportunity to make some extra cash.

I think it's so individual for different people, smbd can buying 5 coins per week, smbd can buy 10 coins everyday, limit it's your own capabilities and needs

i dont put a limit when i have a plan to buy bitcoins,and i also think everyone will not do this. minimum limit for buying bitcoins is decided by exchange,and also people who sell to other people have their own rules,ussually they have minimum limit at 0.005 or less.

When buy there is no limit yet, if you put a cent you will get only dust of bitcoin(satoshi)
All depends on your budget.

But when you sell it min to sell is 0.0001BTC/1 mBtc.

You can purchase or sell as little as 1.00 in your local currency worth of bitcoin ($1 or €1 for example)
Before using any service, it is a good idea to look for reviews and feedback from previous customers. This can be done by performing a Google search of the name of the website or company.

minimum limit for buying bitcoin is where you want buy bitcoin, i mean every exchanger will have some rules for user buy bitcoin at their and some exchanger need your identification before you buy or sell  bitcoin.

i have bought some bitcoin from bittylicious before and only paid a few pence, i would say they have to have a limit somewhere.

Yes every trader has certain limit for buy and sell , but its good if we buy in a large amount at once as you don't have to spend trading fees often.

The only limit is your bankroll. There are no other limits when you trade bitcoins, altcoins or any other type of commodity or currency.
Bitcoin can be divided into numbers smaller than 1 cent, so buying desired amount of BTC is not a problem at all.

Some exchanges do handle a minimum fee to deposit. It depends on their deposit fee.
Suppose coinbase charges 0.0002 BTC on every deposit and kraken charges a withdrawal fee of 0.0002 (this mean you should min. deposit 0.0002 BC)

Yes it depends on the exchanges on from where you want to buy bitcoin, But I think you yourself must also have some mind to keep a minimum limit for you as you should have to buy bitcoin for atleast $0.10, if you want for less than what will you do with bitcoin of worth $0.01.

In theory:  

  X: Quantity

  Y: BTC o Fractions of it.

A)From wallet to wallet to get X  of Y:  Network transactions fee + X

B)Thru an exchange to get X  of Y :   Network transactions fee + Exchange charges + X

But  strictly speaking you can get a  min buy  using A)   where X > 0 satoshies.

Just now: You coud spend 10,000 sat to buy 1 sat then you would are in a loss, So  strictly speaking again
min. buy are 20,000 sat. - 10,000 sat of Network transactions fee to get 10,000 sat.

then there are two answers at least one given by  the  system and another given by  common sense of each one.

There is no limit. Everyone wants to buy Bitcoin at a low price, so the chance will be higher that you can make some profit.
But that is hard to have that. Because it is really hard to make some profit because you must wait a long time for some profit.

Yes the trading fees are also a criteria we need to consider to fix some limit, we have to buy a large amount so that we pay the service fee for once not each time for buying again and again.

I am actually not sure or a minimum limit for buying Bitcoin. Why would there be a limit if you will buy a bitcoin. If you have enough money you can buy as much as you can. If I would have the money as yours I would buy bitcoin for it has a good value in the future..

Yes, bitcoin in the form of satoshi can be divided into much smallest possible unit, so do not put a limit on its minimizing, but the fee of exchange may appear as the limit for the exchange for it.

Ya it is correct the minimum for buying is the minimum transaction fees for that exchange is , because even if you are buying one sathoshi but the fees would be high so automatically you have to calculate your buying with the transaction fees. So now i think so many have given you examples of minimum buying limit.

While in xapo, I have seen that there is no any type of fee, if I noticed right, then it means that the minimum amount of exchange of bitcoin is 1mBTC as it is it's smallest unit I think in Xapo, we can go for.

No needs to use limits of other people. Your own limit is how much bitcoins you can purchase without impact on your routine life like food, car, etc.
You need to determine it  for yourself.

Most exchanges I have seen they have put a limit of 0.01 btc which is approximately 4 dollars to buy or sell bitcoin. but if you are talking about face to face exchange, I think the minimum limit can be anything depends on the agreement between the buyer and the seller

Yes, or exchanges specify a minimum transaction fee. So if you buy too few bitcoins, the fee becomes very high as a percentage of the bitcoins bought. Other than that, even exchanges don't impose artificial limits.

Yeah there is no limitation. Its the best factor of bitcoin getting splitted to required fragments. As quoted by above mate only the transaction fee makes some changes on receiving.

I mean, if its a hassle to get a small amoutn of btc to get from exchanges and pay for the fee.

Most just seek for small micro loans on the loan sections.. then the buying 0.01 approach.

Anything above the transaction fee can be counted as the minimum but personally i haven't set a minimum, as much as i can afford that's all.

I usually bought Bitcoins for around $300 but with the price going up know thinks are changing and you have to invest more money unless the price is going to drop again. That is the thing with Bitcoin the price can switch things up.

hmm never for me there may be a minimum for purchases on an exchange bitcoin. so I just think the limit on the exchange, adjust it

I agree with you a lot of people know about the great potential in bitcoin but they do not see the risk and buy many bitcoin which he thought would give him a great advantage. but I'm sure if the price drops maybe he'll shock for a big loss. if they can not accept it. certainly they will cut lost and sold at low prices. so buy as much as you can afford

There is no limit for buying bitcoin.
It depens what you want to do with it. Do you use it for buying stuff, investment, or trading? So, buy bitcoin depens on your needs.

If you can buy 10btc it's your limit.
If you can buy 2btc it's your limit.
If you can buy every btc all over the world you don't have limit, it's really no limit on buying btc's. 

yeah I agree with you friend all customer know about bitcoin. bitcoin is useful in our future but everybody give advice very different but my thinking is when all customer have minimum 10 bitcoin then everybody future is bright

yeah I agree with you depending on your destination or purposes to buy bitcoin then?
when you buy bitcoin for the purpose of investment or trade. maybe I will buy at least 1 BTC

Depending on how will you use bitcoin for a certain event like in trading or you just want to gamble your bitcoin,the uses of bitcoin depends on the limit you will have.

Is their a minimum limit for buying BTC? because I do not know the answer I tried to look it up but I could not find anything. I was always thinking that there was a limit but know I am a bit confused.

Nope gambling is not a good way to do with bitcoins, It's not good idea I think.
I use to buy and sell bitcoins through local bitcoins.com or I use purchase with local traders. I have bought 0.05 btc is the least fund from lbc.
Hope most of the guys are purchasing bitcoins for halving.  ;)

No limit on buying, if you find a trader who directly transfers bitcoin in exchange for money. Now bitcoin exchanges might have set some limitations.

Oh, nice suggestion, but no one has tried that amount to buy or sell for themselves as, it require some time, maybe one second or half of it, but require time, and the amount you are suggesting is useless, so not recommending wasting that time.

Agree with you, but the time now is the time of halving and double up of bitcoin value, so in that case we have to buy as much as we can, I think we have to convest all of our sphere money to bitcoin so that we double them up.

We are not quite sure what the effect of halving will be on the price of bitcoin. If ever it goes down, then it's like a window just opened for you to add more bitcoins.

I think theres a limitition when to buy bitcoin i think it is based on its supply but if you have lots of money and ready to gamble in btc well its best for now i can feel the halving effect the price is starting to rise daily now and as speculators say it will reach to 700$-1000$ and let see if it really happens. But for now search on program you want to invest to multiply more of your bitcoin.

the minimum amount is not up to us, if you want to trade then it would be up to your exchanger that you are using and it is usually 0.0001BTC as the smallest amount of trade volume
but if you want to send that amount in a transaction then it would be up to the dust rules (it has changed a couple of times so far) but last time i checked it was around ~5600 satoshi (may have changed) and anything lower than that is dust and will go to miners as fee.

That depends on your risk taking capability. If you are young in age, you can use a good percentage of your salary to buy bitcoin to save for future.

For me I am not buying bitcoin using any fiat currency. I do trading and earn in bitcoin. Also I receive altcoins from some free mining websites, which I use entirely to buy bitcoin. SO I am earning around $200 per month from trading and around $50 from other sources like p2p loans and mining sites.

I think there's no limit on buying BTC. But if you mean buying more and in terms of wallets there are limits on it . In my own i do buy BTC ..fiat money to BTC there's a limit on my wallet in my country to buy but if i transfer BTC on my blockchain wallet ,i can buy again amount of BTC.

Depend on the buyer, seller or store, Here in our store there is no minimum purchase, you can buy as low as you can, in seller they have fee for the bitcoin you will buy

No just buy what you can afford.If it's for $10 a month or $100 doesn't matter.
Accumulate as much as you can.But again only with spare money!!
In addition to that go with some sig campaigns or with faucets if you have the patience for that.

Exactly you can buy according to your budget and  what you can afford to, and rather then just buying you should also try to earn it which can be an added advantage in future.

I think limit for buying is your amount of money, you can non stop buying bitcoins till your money ends. I am buying 0.2btc every week cause i don't need more.

Yeah you need to buy what you can afford, as there is no minimum or maximum limit to buy bitcoin, you can buy according to your wish and capital that you hold.

In my country it doesn't have minimum, only few of them using them. But on the internet I found site with minimum of 1 dollar and + big fees,

I invest like $10 worth of bitcoin every month regardless of price, but its more of a act on investment basis.

As for trading wise I do every other day of the week, I try to limit my trades.

It depends on other peoples approach, but I dont like risking too much.

actually there is no minimum purchase bitcoin. but in each exchange has its own rules. so do not be surprised to see a minimum purchase bitcoin is $ 1 for an exchange

I think there is no minimum limit for buying bitcoins. It's depend the exchanger though, maybe there is a minimum for buying bitcoin on some exchanger.

With transactions fees going up then i can't see buying less than that fee being beneficial to the one purchasing the bitcoin. You are going to pay more to send then the actual amount that you are going to receive defies logic.

I am also not sure if there is a minimum limit for buying bitcoins. I guess that there is no limit but do not quote me on that. I would like the answer to that as well because I am curious.

There's no limit in buying bitcoins, as long as you have a good amount of money in your account you can always buy as many as you want. I suggest you buy now as the halving is nearing and its a guaranteed profit already.

It will be bad if there will be a limit and that is because it will be of course really nice if you can buy the Bitcoin at the price low as possible so you can earn more profit later and that is nice.
But the bad thing is that you are not for sure what will happen with the Bitcoin so that is risky.

well the minimum limit for buying BTC here in philippines is 1 PHP because that's the lowest denomination of fiat here in philippines. On other countries like US maybe 0.01$.

There is no minimum I guess, because you can buy even 1 dollar but for the exchange sites they set up a minimum because they also charged you as their service income.

as long as the seller and the buyer agree, it's not an issue then. even if the buyer want to buy a few satoshis or a lot of bitcoins. no limit at all.

The thing is what would you do with a little satoshi, you don't need to buy them because you can earn them even at faucets. If you are just a small investor then you just work for it, and find a job that would best suit you ability as that is more risk free that buying bitcoins.

Dont use those site, minimum of 1 dollar and big fee? That doesn't worth it. You just spent your coin just for the fee.

I am also buying bitcoin whenever i get some money from any source, and after looking the highest increase in the value of bitcoin i wish that i would have a lot of money and i invest all of them in bitcoin to earn much more in shortest of time.

I don't really know but i think that it's not limited, you can get any amount of bitcoin's that you want. But i am not sure about it, it's only my opinion.

If you are talking about a minimum price for buying bitcoin, then the answer is no. I will buy when the price has a big drop after I have sold some so I can buy back more for the same amount of money.

Lol, you buy 1 php and the transaction fee is 4php. It feels like it so nonsense to do so. But I think its the buyer choice if he want to buy on such very small amount.

Well, there is no minimum limit if you're buying through e-currencies. for example, I can buy any amount of BTC I would like via perfectmoney whenever I would like, whether a cent or 100 dollars.

But for cash deposits, minimum is 1 dollar.

I think bitcoin is different, you can buy any amount you want but most sellers would require you to buy their minimum. The good thing with bitcoins is the price will increase when the market is doing great.

Yes, this time is not for thinking that what will be the good price to buy bitcoin as every minute you spend in thinking you lose the opportunity to buy cheaper as every minute now the price increases and will not come back to lower price.

 Few Exchanges have a Minimum limit but you can buy what ever you like to purchaser for the other person, i mean most of the members are here who sell their bitcoins, so if you want to buy it so better is that you should search it in service section and also you can apply the thread that you wana buy the bitcoins, so mostly member will contact you, i think it is a easiest way to buying. otherwise earning is better, you can earn it easily in faucets and in signature campaign.

Now only one month has been remained in halving and at that time a biggest boost in the price of bitcoin will occur and just focus on buying as you cannot earn bigger amount now from different tasks etc.

Hmm.. 23 days to be precise.

http://www.bitcoinblockhalf.com/

I have told this before, and I am warning everyone once more. The basics are still very weak. The usage and adoption is not rising along with the exchange rates. That means that the bubble can burst anytime soon.

Well, the minimum limit for buying bitcoins is depend which site or person you want to buy bitcoin, because every place/person have their own rules when someone want buy bitcoins.

yeah, it mostly depends on the website though you can nearly everywhere buy really small amounts of bitcoins

i think you should buy enough bitcoins for your investment that you could earn some decent money

how do you know what is the correnct number of usage for the current price? maybe $430 was too low for the current usage, one never know, and maybe $1000 is right for the current people that are using bitcoin, just my opinion

I think now he should have to invest all of his wealth in bitcoinif he really want to get bitcoins and to earn profit from it with increasing value, otherwise he will toss his head to the wall that why he did not bought at that price.

You only invest what you can afford to lose do not invest all you have, there is no limitation on buying bitcoin you can buy how many as you want but look for the risk of it. Just take care

With all investing it is worth it to budget yourself properly. You know how much you make a month and also how much your expenses like rent, utilities, and food will cost you. I'd advise, conservatively, 20% of the remaining money to go into a Bitcoin investment depending on how much money you want for entertainment. If you don't have any interest in other things and no other investments then a liberal 40% would be obviously more money into Bitcoin investing.

Definitely, that's what I was saying. You could literally buy 1 satoshi of bitcoin, but that would probably require a ton more in transaction fees, which is why most sellers settle with a minimum.

The minimum for cash deposit to BTC transactions is usually around $1-50.

If you are buying bitcoins to buy online products to sell then the cost would not matter to your because you will add up it to your purchase price and will put mark up when selling. But when you are buying in for future investment then better buy it in bulk to save transaction cost.

Most exchanges charge a percentage for the transaction fees, so you can just buy 0.001 bitcoin, without any problem.

You could buy one Satoshi for $ 100 simply because it came from a celebrities wallet, or you could buy that same one Satoshi for 0.00000001 Moon Coin because you feel both coins are of equal value.
