Obvious altcoins shoudn't be in the discussion here, it should be between holding Bitcoin or trade all profit to stablecoin to remove the risk totally. Both holding Bitcoin or stablecoin are perfect options but it totally depends on what your game plan is. Are you okay with the amount of Bitcoin you currently own and just want to hold forever or until it reach your targeted price. Do note also that nobody can predict the button but can only speculate on the range so don't be fooled by any article you read out there.
If you know you can hold through all the downside that the market is likely to experience in the coming months then keep your coins in Bitcoin and just take your mind off the market until maybe when the bulls come back. With holding in stablecoin you'll need to monitor to market to know when to buy in which might come with alot of pressure. But if you can manage all that then holding stablecoin has more advantage.
