My main coins are BTC, ETH, LTC, and XMR for obvious reasons
My purely speculation coins I have are: ARK, GNT, XLM, ARDR, LMC.
Here are only a few out of other reasons why I invested in each for my speculation coins..
ARK - i really enjoy the subreddit community there
GNT - team does a lot of events... Brass 2018
XLM - i dont know
ARDR - i like the look of the company. some FUD there (with non patient investors) but theres an underlying current of smart hodlrs there i believe
LMC - honestly seems like a pump and dump to me (a NEWB). Absolutely no dig to the investors there, im one of them, i just like the app they have and I see the Potential.
