Bitcoin is now almost at its bottom
There's no way for you to know that.
and i do not think it can go below this point.
Thinking something is impossible is a terrible investment strategy.
So i will suggest to invest all of your savings in bitcoins
Putting all your money in something as risky as Bitcoins is, generally speaking, a very bad idea.
Don't invest more than you can afford to lose, and use diversification as part of risk management.
as we may not get this low price of bitcoins and altcoins anytime again.
Maybe, maybe not. You can hope for it, but you can't time the market.
