I like Gravium and Stim, I'm chasing masternodes at the moment but those are my current picks
But why? I also like Gravium simply because the new dev team seems professional and I like the way they handled the swap from DSR. Other than that, they are doing solid technical work with MN support and listings but I still haven't seen exactly what makes them special. It is already far better than DSR ever was but I still want to see more clarity and I realize that may take time to be seen.
The masternode scene is hot right now because of the attractiveness of passive income. MANO coin is newer than GIN but has already overtaken GIN price and already has as many if not more people supporting it. It is difficult to obtain by mining and the price just keeps going up. And... I understand why MANO is important. It basically has to do with a shared MN platform which will be better than any most people have seen. Discord is okay but VERY risky to use for shared MN platforms. There are some good ones in discord but a more automated platform is what MANO will have ready and I think they'll have it before GIN does even though GIN started before MANO.
So yeah, my vote for speculative coins to mine is pretty much with MANO but like I said... it also has a high difficulty right now.
As for Loki.. I know it has some support. I mined it for a while. looked more into it... didn't really see anything mind blowing... idk. Seems similar to snowgem promoting when it started.
There are a lot of really good projects right now with really good people behind them. I'll just sum up by saying I'm following:
Criptoreal :: B-hash :: MANO :: Gravium:: Weycoin :: Smartcash :: Rebl :: Absolute :: Bitcore :: Bitsend : Yenten : Innova : EXTN : Arionum : Zettelkasten : CRDS : POWR : NEM : SEMUX : Cerberus : SCRIV : Veggie : Polytimos
And I'm sure I left out a few... and several 0x tokens lol... some of which can even be mined!
