because buying back or trying to do it at least is a lot of risk too. first you have to sell and cash out to your bank, since you can not leave anything on exchanges.
then if nothing happens after Aug 1 price will rise up so fast you can't even blink, then you come in and decide to make a fiat deposit. it will take a very long time until your deposit reaches the exchange (not to mention it may fall in weekend and take longer) then you will end up buying on top and miss a good chance.

not to mention all the problems that cashing in and out a lot of fiat to and from your bank has. specially when you are doing it to a bitcoin exchange!

you did the most logical thing. it is stupid in my opinion to never sell anything the same way it is stupid to sell everything just because price dropped a small percentage!

you buy when things are calm and low then sell a small amount to celebrate your profit and then shut your eyes and ears to all the drama caused by small fluctuations in short term.

result: you will have a lot more money than those day traders trying to beat the market.

a quick google search brings up very good results;

and be careful not to fall for anyone claiming to be in one of these groups and claiming to be real and profitable. they are only profitable for the group owners.

no it is not true.
because it is not a simple thing to easily point the blaming finger at someone or some group of people. it is the combination of all our mistakes and arrogance.
the miners for being greedy and arrogant to want to secure their profit and make more of it.
the fault of developers for not communicating well.
the fault of users for not educating themselves to be able to make a decision, run a node and support something already!
and finally the fault of those who messed up everything with their BU delays. instead of creating a new thing out of bitcoin they could have stuck to what already is accepted and prevented all this prolonged debate.  we could have finished the scaling debate 6 months ago if it wasn't f or BU

it depends on how much money you have invested in bitcoin!
for example if you have invested your whole life savings in bitcoin then the third option is a must do.
but if it is a smaller amount that you can handle and afford to lose then your options become wider.

right now i can't see any altcoin that is good to hedge against. they are known to fall when bitcoin goes down which means even bigger loss!

i see someone suggesting litecoin, it is a good option but i would wait a little until it bottoms out and then invest in it to increase my chances of making an even bigger profit.

whenever bitcoin falls, altcoins fall harder. it is never the other way around (selling alt to buy bitcoin). that is not how things work.

and if you look closely alts have been in a very big bubble for some time now which is now bursting. it actually started a while back before bitcoin had this recent drop of today. the drop just became faster when bitcoin experiences this dip.

and also if you look more closely not all altcoins are dropping. some are still there keeping the price up.  but only those heavily pumped alts such as ether are biting the dust and going down fast.

you need to learn how to manage your investments well. that is why i always say don't go overboard with your diversifying. when you invest in a handful and manageable number of investments then you can manage them easier too.

drops rarely happen fast, and even if they do, it will still be step by step drop. for example if it is a 30% drop in an altcoin price then it will happen over a whole day. and when you are watching the price you can catch these drops as alerts or whatever other method you use and act on it fast by selling at a small loss (like -10%) and save up on further bigger losses (preventing 20% loss).

if you can't already make up your mind on your own, then a random "anonymous" person on the internet whom you don't even know can not do anything for you.

so don't buy.

then you have been reading the wrong articles so far.
and don't compare bitcoin with eth. eth is a centralized altcoin with no consensus mechanism despite what they pretend. and its fork was a roll back to protect the pocket of the main whales because the messed up and got DAOed.

existence of centralized exchanges and how they work does not go against the nature of bitcoin and does not change anything about it being a peer to peer network without middle men.

(centralized) exchanged are good places to do high speed trading. decentralized exchanges does not (and i think can not) offer this.

nah, it is not really impossible.
people thought it is impossible when price went up to $10 (1000% rise).
then they were skeptical when it went up another 100% to $20
and they certainly never believed price will go up 900% to $200
and again they were skeptical about future but price went up another 500% to $1200
and when the drop began in 2013 they gave up on bitcoin and when it reached the bottom at ~$200 many said no way it will go up again.
then price went up another 500% back to $1200

you can actually see their comments 10 or 20 pages ago in speculation board saying $1200 is the bubble and things look like 2013 and will fall back down to $200 or $600 but despite all that price went up another 140% in a couple of months and still stays up above $2500 very strongly.

and there is nothing stopping bitcoin from more adoption and more rise. 200% or at the very least 150% each year.

#history...

the answer is the same as the answer i gave to people a couple of months back asking "why prices are going up?". it is all about the pump and dumps. when prices are going up everyone is happy and nobody cares that all these altcoins are going up for no reason (getting pumped) now they are getting dumped for no reason too, as the investors take their money out of them.

when you invest in bitcoin you accept the risks, when you start to pick up trading too then you have to also accept the risks of trading. and there are a couple of big ones like exchanges running away or you making a couple of  bad decisions that can easily lead to losing half of your capital.

that is why in my opinion if you have been long term HODLer so far, then continue being that. don't try to jump in unknown waters just yet.

he is not talking about "bitcoin credit card". that actually would be a silly thing to say the least. if you want to go through a third party aka a bank then stick to fiat, it has less volatility and possibly less fees than bitcoin cards.
what OP is saying is using bitcoin itself, more like directly or just carry it to the other country as an easy way of transferring money then convert it to local currency.

i can only think of work arounds like these:
1. open task manager and find the trojan and do a end process. sometimes it works on some of them and they don't come back.

2. since it only changes bitcoin addresses not other copied data, if it was possible you can always add some arbitrary data to the address you copy. like adding "abcd in the middle so it becomes an invalid address and then after pasting remove "abcd".

3. use BIP21, you just click the link and it automatically opens your wallet and fills in the blanks. this needs to be tested but i doubt it can be affected by that trojan. it will look like this

you can check this topic where i asked others to see what they said, there is also a list of some of the explorers others have used in there and also you should move you topic to services discussion board.

i am sitting here using the old noodle to see what the binary part means! that thing is not binary.

this is its binary:
1101010010100110001010101011001001000011101000000001001001010001010110110010100 1011001000001000000111011011001111110011100111110001000111001001110000101001010 0111111000001100000101111111010010011101000000000000000000000000000000000000000 00000000000000000000000000

and this is its private key:
6A53155921D00928AD94B2081DB3F39F11C9C294FC182FE93A00000000000000

but has a different address...

the data from coinmarketcap is not live, it updates every 5 minutes.
if you want a live price you have to use an exchange API to get the price data directly from the exchange not through a third party.

for example call this:
and then take the "Last" key or "Bid" or "Ask" keys for respective prices.

1. i find this weird LOL
2. this is not bad, if you have the time
3. this is the best option but it needs 2 things first. first is the customer or people who already hold bitcoin to want to spend it in that local vendor and the other is the regulation rules, for example what the government says about bitcoin, what are the taxes, ...
4. i have actually done this once when price went up the first time. i used the profit to throw a party
5. this takes a lot of innovation and i lack the talent 

adding 6. tipping on social media. when changetip was around it was a good way of tipping others bitcoin and introducing them to bitcoin.
