Say the coin ripple is good, banks invest in it?
Yes investing in ripple is worth, as you said many banks are invested in this coin and NEM and NEO is also good coin to invest before this year end.
I think many banks are interested in supporting Ripple and this is the one reason why it's value was rising high and people showed interest in it. If you talk about Neo, this coin is good because it has less supply and all those coins whose supply is less their value grow much more faster than coins who are more in supply.
