It is all gambling at the end of the day... having said that.
bitbay - talk to the dev then decide
blocknet - research hard and see if you like it first - huge potential but taking forever to get this out.
-------------------------------------------------------------
coval - risky but i decided to get a bit - hard to find good info but there was some promising snippets
cloak - seems to have some good people coming on board. got a little bit not 100% sure
xby - intersting but not sure yet
cbx - like their new road map
quark - big one that went to shit have a new team I have a bunch and accumulated more lately - risky but may be worth more research
sys - another possible interesting one.
pivx - another good one but I sold too early
Then those are maybe the worst gambles you could make in the cryptospace. What are your profit exits for each and how long are you planning on holding them?
You have been here longer than most of us yet you still give us bad investment advice.
