As an altcoin investor, you only need to hold the top few altcoins. and do not forget to always monitor the market situation and also the assets you have, on the one hand update altcoin that is difficult to develop.
To the few top altcoins, a trader has to monitor it daily so that he can calculate the profits that he's gaining. Otherwise, the same as being a bitcoin holder, a plan of holding it for long term no need to monitor it because you just leave it and wait.
I am holding a few XRP and ETH and they are making a profit for me right now. However, I still hold them and waited for the Bitcoin price to peak and stop, at which point I was pretty sure the prices of the altcoins I was holding would increase more than they currently are.
Eth is ideal.
Proof of stake is about to blow and everyone is busy stacking up their at least 32 ETH to be eligible. AFAIK, there will be pools that you can contribute even you don't have the minimum req.
