It was said for many times - invest in the crypto currency only the money that you are ready to lose. Loss of money is your personal risk and responsibility and you can not blame someone other than yourself.
Invest small amounts, experiment and only then invest the big money. But again - do not forget about the risks of losing.
The field of the crypto currency has not yet been adjusted with Law and nobody will take care of your deposits. Except perhaps professional traders who will take your money to work, but this is also a risk, albeit smaller.
Think with your head, do not seek for big profits.
And in general, what is the loss - have the courses dropped? You can wait, because the courses can also grow.
