poly is trying to do something new and needs some time to grow into that. I havent researched the company properly but from a quick look the team seems good and they are moving forward. they will need some partnerships. I lost a lot through Q1 and got burnt on some coins but i refuse to sell at a big loss. this means i'm holding some coins which aren't moving but so be it...ill keep holding them because i've spread my investment out over a lot of coins. they may never come back they may also moon so...up to you. if it was me i'd hold. If all your $$$ are in poly maybe thats a different thing
I actually sold about 2ETH to invest on Polymath, so no its not all of my money there! A fun fact it that with that low supply it would be soooo easy to double my investment or even triple it! But is Polymath ever gonna do its thing? Who know...the idea of the project i would say is very strong and when I invested I really believed on it! I think I'm gonna hold this one!
But Sp8de?
Considering that they (SP8DE) were announcing saying that it was being developed in the Cardano Blockchain and the CEO himself (Charles Hoskinson) mentioned that it was nowhere related to ADA(Cardano), it's probably most likely a scam.
That being said, I would definitely not trust it. No idea about Polymath though.
Maybe their vision is to intergrade into ADA blockchain when their project will a reach the stage of implementation!
