Is it possible to earn 1000 or atleast 100 bitcoins with trading Altcoins.If I buy some bitcoin at cheaper rate today and it's price goes up in future?Which alt you think has potential to make me 1000 btc
this depends on a lot of things, so it is both possible and not possible based on you and what you are doing.
if you are willing to take huge risks and invest a lot of money and your time in trading and also do it right and not just gamble with your choices then it can be possible but if you are not good at trading and also have a small capital or you want to take lower risks with smaller amount then it is not possible.
