I'd probably stick with the tokens I am holding right now in order to avoid mistakes on choosing which other alts would be profitable investing if ever the price starts to rise. It is a way to be safe from regrets since if ever there will be a price increase, we don't know how long will it last and if it would positively affect ALL of your holdings. But it would depend on how confident you are as an investor especially if you really trust such coins of your choice.
