when the Bitcoin price keeps going up what are you doing now? hold it or be traded with altcoin.
I'm stuck in a very difficult situation now. I suffered losses in some altcoins that I bought for a high price. some rumors say that prices will be rebound back next month.
However, I'm confused better to hold altcoin and sell it after the price recovers or sell all altcoin to get BCG?
someone please give me some advice

I think you should be ok after the forks are over. The same thing happened with bcash. After the fork ended, and people managed to dump their free coins, they then invested it back either into the main coin or into alts. So all the capital raised from these two forks, should then be tunneled back to BTC and alts. Selling now and buying BTC would still be a good option. After the forks are gone, you should analyze the situation again.
