So with the current dip happening as we speak TRX is at 3c and Neo is at $67.
Now I have 1.2k remaining

ready to invest for a good return. Should I:
1)Go all in for TRX at 3c and hold till test main net pump and dump it?
2) should I invest it in Neo?
I think you should go to NEO for invest. because in a condition of correction, while, I do not rate the value, but I see the credibility and quality of altcoin.
and NEO is altcoin can to survive stable and sometimes rise when correction today.
