Pepecoin for sure man its the one with some serious tech and active development behind it
Reasons to BUY and HODL
1)Masternodes a.k.a MasterToads
I have 2 nodes running right now and pull about 20 USD a day from them at current prices
2)Kekdaq.com, seriously cool Exchange for MEMEs and you can even create your own tokens see this guide
https://www.docdroid.net/EgC2rmd/pepecoin-burning-guide-kekdaqcom.pdf3) Its on Bittrex listed as MEME no other memecoin like kekcoin or pepecash is listed on the best altcoin exchange like bittrex
4) Very cheap its been around 3000 satoshi for so long now and with the amount of work the devs are putting in its easy 10x its a sleeping giant
