I think to have a bull market up-coming is the best way to move all the money that you have in altcoins to bitcoin, because with market dominance of Bitcoin the market will go green, and the bull run with start, as far as I am concerned from the previous experience of the bull run more than 55% bitcoin was dominant in the market.
Suggestions?
How could you forget about diversification? Even if you are 80% sure of your idea, you still can't do that. You understand that the market is constantly changing and in the end you can lose a large share of profits because of their rash movements.
