Not mining. You can do whats called harvesting. You need a minimum of 10K NEM and you get fees from any block you solve (if it contains fees).
Or if you have 3 million+ NEM, you could run a supernode where you get fees and a daily payout. Probably not an option for you unless you are a whale 

I use to get some nem from harvesting, now I never find any blocks. The last block I found over a month ago contained 0. Yes I check to make sure the harvesting node is active. This is with 20k too!

You should still respect decisions you made in the past.

Cryptoland is young, there will be new opportunities.

There might be good opportunities in the future, but I doubt comparable to nem

This is why you don't sell all.

If ye don't have faith in the project, keep at least 10%. You never know if in a few years it comes back bigger than before.

Currently Zaif tokens are issued on the Counterparty protocol, but since there are no safe and stable tools to create multi-signature accounts on that protocol, Tech Bureau will migrate Zaif tokens to the NEM protocol which has a secure multi-signature capability.
