Out of these 3 these two are my favorite, Sys coin and PIVX.
The Syscoin Blockmarket Wallet offers all the features you need to send and receive Syscoin, keep your transaction logs in order, buy and sell items, resell others items, send encrypted messages to others and more.
PIVX price as at the time of writing this is just above $5.06. This is insanely cheap. For a coin with just 55 million in circulating supply, I can’t even begin to express how cheap this is. I think its better to invest this time or are you wating for further price drop? Please do inform me if you think so.
