holding an altcoin is the best choice, but if you look closely at the annual altcoin it can make speculation how we can choose a good altcoin and potentially get an annual profit.
I would rather be trading than staking honestly. I have tried both and considering the fact that most altcoins usually a lot of the time, tend to erase their previous gains to almost a 100% for instance like NEO and the likes, why on earth would I want to keep holding them when I would have used the gains to double my holding eventually, and that is something staking will never give no matter how much of it you are holding.
However, it is understandable that not everyone have the ability to trade, so it is not like if you have no other option, staking cannot fill the gap, but as a trader, I do not see it as the best option for profitability.
