Personally, No, I would rather stick to the top 10 coins right now as the market is really very volatile and unpredictable so the risk factor is high, at least for me.
Wise choice but your leaving an opportunity to find out some hiddem gem too. If you just do some bit of research there are plenty of altcoin that have potential though you might not trust me so its fine. I think, you will know once a project has chance to be something big later on. For example, cartesi project. It has a unique approach towards blockchain using capabilties of linux. Well pretty new, but not different to some platform but their idea is much better. Anyway can blame anyone for not risking something here due to many people have been lose due to market crash of altcoins.
