Re: what is the best decision

The only thing you can do now is just hold. You didn't loose anything until you sell.
If you did the right thing and didn't invest money that you need, you'll be just fine next bull run

I strongly agree with the opinion you convey, in my opinion the development of the crypto currency depends on the investor itself

I agree too. The best thing we should do is to hold and wait for the bull run or at least bull trot. Because last December probably won't be repeated.

The best we can do today is to start investing in, sir, believe it is the best thing you can do for yourself and for the market as a whole, because this is the way the right prices are formed in the market.
