I foresaw the recent 50% jump, though forgot to post it. I still believe it's got momentum to hit an additional 98% target in the next few days. Though this trade is still risky, hence the ~25% stop-loss, thus I do not recommend investing more than half your pot.
I believe it will continue till it reaches the $77.5 target. But I still think that right now NEO is a somewhat RISKY SHORT TERM INVESTMENT - especially with BTC ralling to $20-23k levels VERY soon - and would not recommend allocating more than a quarter of your portfolio to NEO.
