First of all guys, look at what part of the forum this is.
Any ideas what to buy now and keep for longer?
The big three still the best crypto to invest Bitcoin, Ethereum, and Ripple. These three are the largest market cap
which secure us in terms of coins stability in the market. Aside from that these three are tested also from market vulnerability. Ethereum price almost maintain it's price despite of big cash-out from the market. This are the reason why I'm backing up these three crypto.
Largest market cap is not all upsides. Yeah it's well known and traded alot, but also has less room to grow. Ripple is partly centralized, and is pretty high priced compared to how many is in circulation and the total supply. It's success is also heavily dependant on the banks taking use of their product xRapid
A lot of people recommend iota, and while that's understandable.. keep in mind that they don't even have a working product. Network and wallet problems.
My longterm ALTCOIN picks - NANO, NAS, ONION, PRL, NEBL, EDO/ETHOS. A little riskier, but also alot of gains to be made. Do a little research on these coins and you will understand why.
