Many find it hard to invest any money on bitcoin or altcoin but now that we are in a good crypto year I think its wise if you hold few good top coins but if you don't have any money make sure you hold parts of coins or tokens you earned from bounty, remember what happened to most bounty rewards in 2017?
2017 success ratio can never be repeated in the space anymore since the like of ICO that triggered the hype are long dead. The market might still recover and even surpass its previous all time high but not all altcoins will be carried along and only few selective ones will benefit from bitcoin price and the likes of ethereum will be among those coins Your suggestion isn't that bad since it'll also contribute the decreased of these spams
