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

Never chase a coin. If you have to ask others or advice on this then you need to HOLD. Chasing profits will get you nowhere. If you want BTC Gold then invest more cash into BTC, don't sell your alts at a loss. History says that the alts will bounce back.
Also, you havn't lost anything until you sell.
