I think its yes. It is better to keep holding bitcoin until it reach the highest value of it. Bitcoin is like a kind of gold that can keep and has increase annd dicrease of its value. It is good way to make money while keeping it.
Yes that's the best thing to do right now is holding your bitcoin. Because I did hold bitcoin when the price was at $800 and up to now, I still hold up to now and the price is $1,759 and it was close to $1,000 profit. And if you believe that you are going to get profit with bitcoin, then just keep on holding so that you can have good money.
