Have a look at Byteball. Strong fundamentals and a nice reward for holders. If you own some BTC, you should also participate in the GBYTE airdrop for BTC holders.
No problemo for byteball to rise 3x, a great tech, the creator of NEM is behind it and look where is NEM now. There"s also a rumor that Lisk foundation will have an airdrop of byteballs since they are the biggest holder.
