I prefer altcoins which gives stakes automatically, i.e. not to run an open wallet.
Even though the price gets lower, you will get something extra to decrease your pain
NEO, Waves are such ones. Vechain was expected to introduce staking but I don't know the final situation.
There is a very succesful project, tomochain, which will have an interesting staking algorithm, that you will vote for masternodes with your tokens and share its rewards.
There is Aelf bounty program which gives interests to your dropped coins.
Lastly, mannabase is giving away weekly free coins, even though it is very cheap coin
