your option lacks the most appropriate response in my opinion: All of the above.

it really doesn't have to be only one of these reasons. it can very well be all of them and more. people can have many different reasons, some start from one reason and continue to others. for example i liked the fact that i could earn money from bitcoin and how profitable it is but later on i did some research and found out about what it really means and that led me to investing in it not the monetary gain.

just try not to get emotional when you are making the decision to invest your money.

not everyone. at least it is not their 100% intention. obviously everyone loves profit but many want bitcoin because of what it does not only because it has the potential to give them a huge profit.

not for a very long time.
the adoption is a process that is slow but the speed of it increases. it will become very fast in a period of time and when the adoption grew big (aka mass adoption) then the rise slows down. this won't happen for years.

it is not just hope. it is more of a fact to me! majority of people don't even know about bitcoin or they are greatly misinformed. like when they read an article or see something on TV where it calls bitcoin a fraud! they obviously stay away. but then they see huge companies in the same country are accepting bitcoin (like Microsoft and Dell,...) and then they realize what the bullshit they heard. slowly more people find out about bitcoin or correct their understanding and start wanting it. that leads to more adoption and higher price.

it still believe that all the news about China has been greatly exaggerated which makes it big FUD. and because of that i am afraid we are not going to get rid of Chinese anytime soon. and it is pretty bad if things continue like this! as it was mentioned before, we have this drama about China for a very long time. i believe the first one was back in 2013 when they prohibited banks and other big financial firms from investing in bitcoin. and that news came out as "China banned bitcoin".

if someday they do really ban bitcoin we will finally have a lot less drama in bitcoin and hopefully the biggest source of FUD will be eliminated.
as a result bitcoin will go on stronger.

people think all kinds of weird stuff these days. let the next bitcoin rally start and their thoughts will change too...
if you don't believe me you can check the majority of articles on news sites for the past months when the rally was still ongoing. every article was about how bitcoin is not a bubble and how it is rising and being adopted an will be $10,000 by the end of the year.
now they all change subject!

steemit is not a valid source! people post there to get paid so they try their best to post something that gets more attention even if it means providing false or exaggerated facts.

besides people who invest in bitcoin aren't really publicly releasing statements about where they got the money from so that we have any statistics whether they are really getting mortgages or not.

bitcoin price is always "creeping up" that is what makes it a good long term investment.


it depends on who you think you are!

if you think yourself just an investors who have invested for long term then why do you even bother with these small fluctuations. you just keep holding what you bought in the dips and if you saw a huge surge you can sell and buy back in the next dip.

if you think you are a day trader then it is a very different story. you can take each day's highs to sell some and and buy back in each dip. that doesn't really change when price is $3800 or $380000 the strategy will be the same and profit percentages are usually low even 1% can be an option.

it is B (Byte) not kB (kilo Byte) i really doubt you had a transaction as big as 487 kB! that is half a block size...

it depends on the "situation"
you should trust Electrum to give you a good estimate. it has been good so far that i am using it. the "situation" is based on the number of unconfirmed translations in the mempool and the fee that others are paying (the competition). when the competition is fierce you need to pay higher amount and if you pay less your priority will be low so your transaction will take a long time to confirm.

for example 6 days ago i sent a transaction with 4 satoshi/B fee and it was instantly confirmed (a couple of seconds as 1 block was found immediately after i broadcast the tx).
but today mempool i full AKA there is competition so the same amount of fee will be low priority.

practically every exchange is working like that!
you "convert" something to something else on their platform. for example you have BTC and want USD, you exchange it for USD and keep it there until you buy back again and have BTC again or anything else you want to do.
when you sign up on an exchange you get "an account" which has all these balances which you use to trade with.

why is everyone giving mempool status for these coins

here: https://bitinfocharts.com/comparison/transactionfees-btc-eth-ltc.html#6m
this is the chart for Average transaction fees for these 3 cryptocurrencies you asked in the past 6 months.
play around with the options below to see other time frames or other data like the Median transaction fees:
https://bitinfocharts.com/comparison/median_transaction_fee-btc-eth-ltc.html#6m

and remember these are averages which means they consider all transactions in blocks in the period representing 1 point on the chart. a transaction fee depends on many things such as size of the tx and other factors.

oh my god! i have not even realized this but 1 satoshi is equal to one unit of the Iranian Rial. 1.29 to be exact but it was a fun find

1 satoshi = 0.00003871 USD = 1.29 IRR

i disagree.
this is not the first country to take a weird stance towards bitcoin. and this is not even the first time that FUD about China banning bitcoin has come out. other countries don't really care about what China does. they make their own decisions. otherwise all other countries would have adopted bitcoin when Japan did! you see it goes both ways.

this $4000 that happened about 12 hours ago was a recovery from the huge panic sell that occurred over the past week. now the market is more balanced in my opinion. whether this upward trend can keep up or not remains to be seen but i think it will not be easy at this point. we may see some stability with smaller fluctuations from now on until the next drama.

will it make another low? it may go down but it won't be another low.

but in bitcoin most of the time unexpected things cause unexpected changes. we may see another wave of FUD that causes another drop, or we may see something unexpected and price shoots up. what i said above is my speculation in case nothing unexpected happens.

this is such a weird article. and the choice of words in it are pretty interesting. it shows the purpose of it which is in fact mostly FUDing bitcoin. words such as "computational wheel spinning operations" and "artificial work" are what stand out to me.

... and they keep bashing bitcoin for years and years to come. but bitcoin is going on strong and disregards all the B.S. of the media. the real panic comes from those who are bashing it.

The Users!

bitcoin is a decentralized system, it is as powerful as its users. if the users understand the meaning of decentralization and try to keep it that way and educate themselves, nothing can harm bitcoin at all. but in case people stop understanding, trying, educating themselves,... they will kill bitcoin on their own and the enemies don't have to do anything!

actually "We" as in "ViaBTC and bitmain who sells mining equipment" not even Chinese! people can continue to use bitcoin, even miners may be able to continue working fine but big companies that have been selling "cloudmining" aka ViaBTC or mining equipment aka Bitmain will be fucked.

it depends on how much i own and how much i am willing to risk.
for example back when i owned <0.01BTC obviously i would have invested all. but if you have bigger amounts it is going to be highly risky to invest all you have.

just set aside some funds that you feel ok with and start trading with that.

it depends on the coin.
bitcoin is the long term investment of mine that i have been holding for 3+ years and i will continue to hold it. meanwhile i have also done some trading too.
altcoins are usually different. they get pumped and the pumps take from a day to a week and you need to find the end of the pump on a case by case basis and sell before it has ended.

well you buy as much as you can afford to lose. don't get greedy just because price is lower. sometimes it is good to take a leap of faith and take some big risks but in the end you have to act wisely. taking big risks should mean you have accepted the consequences in case the situation went against your expectations.

in any case, yes i have bought some in that glorious dip like i always do. most of what i have bought so far have been in big dips.

no, it is not about how much you invest in bitcoin and not restrict it at all. you can still invest 10 trillion dollar in it
it is mostly about spending bitcoin. for example if you spend $100 to buy something from Amazon with bitcoin right now a good little obedient citizen has to fill the tax report and report that. but with the new bill you won't need to do that and it will be legal.

again with this picture! at best we are in the Awareness Phase and in the first "Bear Trap"

and if that is not sufficient then look at the charts and how price changed!
price went from $4979 to $2972 that is $2000 drop or 40%!
if you still think there is a bubble then you don't understand what a bubble means!

any third party service that offers "accounts" can simply seize those "accounts" if they feel like it and they reserve the right to do so. there is also a long ToS that you need to read and understand and if you break it they can again seize that "account".

that is how centralized services have always worked from the beginning of time.
if you don't like then, don't use them.

by the way the article you shared is a complete FUD from someone who doesn't understand bitcoin.
example of idiocy:
