Focusing only on the top 5-10 alts isn't usually the best strategy, probably better off just holding btc in cold storage instead. Last year's top alts looked quite a bit different than the current ones. Goal should be to find solid crypto projects across the various major sectors with a good r/r who seem most likely to make big moves over the next 12-24 months - with the exception of maybe using small amounts for daytrading, arbs, etc.

Many of these are currently sitting at or near lows. Always DYOR and make thoughtful, informed decisions. Lastly, be aware of counterparty risk and try to keep your coins under control of your (and yours alone) private keys as much as possible. These recent 51% attacks on a few smaller PoW alts have demonstrated financial risks that stretch as far as the exchanges themselves in many circumstances. Stay safe out there!
