Rather than that.... Keeping 40 btc Is still trading because btc price will eventually go higher
Or you can invest for longterm in major promising Altcoin like Ethereum Dash XMR or Litecoin... etc
Well the cryptos that you've mentioned are also following the trading patterns of bitcoin for the most part, and apparently bitcoin is also doing good amidst the drama that is currently on going as to where are we going from here. I suggest that you just keep it as it is since the growth wouldn't stop here; there's a lot of money to be made in bitcoin. But to don't miss out on the opportunities, you can always try to diversify your assets.
