I have not heard of these altcoins before, thanks for the post. I have followed, upvoted and resteemed.
Have you ever heard of waves? It is a decentralised platform that requires a minimum holding of coins to mine so you can rent/allocate your coins to miners for a fee.
The great part is that you hold your coins the are not transferred.
Yes I have heard of waves but have not spend much time reviewing the coin. Did not know its feature with mining and will have to research on it. Thanks for dropping by.
