Haha, just read this story in my email. Some comments.

Potcoin. Just for fun this was one of my earliest coins after btc and eth. I made a very nice swing trade for some nice gains. For whatever reason, I've never bought it again - don't want to ruin a nice memory I guess. At any rate, if mj continues to gain legality in US, as it appears will happen, I'm not sure the reason for these hemp coins. If dispensaries can use banks, I suspect they will. I think the dispensaries here in Cal accept cards.

Factom. AAAAAAAAAGGGGGGHHHHHHHHHHH!!!!! Such a frustrating coin. I've held this thing forever and have tried to buy in troughs and average down. Still not working.

Presearch. What do you think of Nebulas - being touted as the Google of crypto. Are these coins doing the same thing? Of course, that's common in crypto.
