Bitcoin

[uls]

when all 21 million bitcoins are mined then they just exist out there in circulation

whether the world uses bitcoin for daily transactions we'll find out later

bitcoin proponents are saying bitcoin will become the currency of the future

salaries will be paid in bitcoin, everybody will buy and sell stuff using bitcoin

but there are so many alternative coins out there

litecoin, ethereum, monero are most popular after bitcoin

altcoins are competing with bitcoin for the world's attention

some time in the future, one crypto will become most widely used in transactions and it will be king

if you invested in the right crypto, you'll be rich

the value of other cryptos will fall to zero wiping out the investment of those who bet on them
