Can you advise me some coins on which to invest in middle / long term except bitcoin (too expensive for me...) ?
I already have some Ripple, Dogecoin, Iconomi, ETC and Lumen.
Thanks.
Just keep on holding Ripple and ICONOMI they have a very good future. Have you seen what's happening with LTC?
I guess you need to have some of it too, also why monero isn't on your list?
It will be a good set of alt coins that you've got if you will include those two that I've mentioned for you to hold.
