I'm currently only invested in Bitcoin, Steem and Monero and I'm not really looking into any other coins at the moment.
The reason why I'm only interested in the above coins is because I know those coins inside out and use them pretty much daily.
I personally don't like to invest in something that I don't make use of personally. Probably a bit weird though...
Thats fair enough.
I dont use any of my investments. (i simply buy and hold) but currently i am moving some fiat into:
Deep onion - Not listed on many exchanges yet, low supply, great potential for the future
Neo - Very solid project - i consider this one of the safer investments
PIVX - Dash fork, very strong team, working product
Cardano - Again strong team, great potential - but they seem to be pretty slow with their movement due to wanting perfection - could be seen as a good or bad thing
ARK - Interesting project, the best wallet out there IMO - If they can pull it off i see huge gains for ark.
I am invested in over 30 cryptos (Very small investments) , but these are the ones that have my attention for now.
I think for a safer ride platforms like ETH, and Neo are safer options as they are not one trick ponies, privacy is also big which is why i also have invested in XVG, deep onion, and PIVX, and also look for cryptos that have actual working products for better security.
Many of my investments are based purely on speculation an they dont have working products yet, but there is huge potential if they can pull it off.
Just my thoughts
