Hi I just got some extra money and I'm looking to invest, I want to invest in BTC but the price is too high for me, what do you think will be the next BTC
one you can buy low and make a good profit when it burst?
From your statement above, I can see you have not educated yourself first.
Investing is a plan you developed not a get rich quick scheme.You have to spend time more on understanding what cryptocurrency are before you think about investing your money. Take time to study the tech behind any project you feel is an alternative or got suggested to you via comments as you don't want to invest in bitcoin because you feel it's too costly don't forget there are only 21million available.
Very sound piece of advice. Your decision should be based on your understanding of the crypto rather than just on a desire to spend money. Only then you can hope for success, imho.
