I did not invest in it to exit for two days after listing. I invest in it because I believe in it, both in ideas and economics. However, Bitfinex is a good place to start.
Are they going to list token to some other top exchanges? And when swap to original coin and mainnet launch?
Your second question reveals that you didn't read whitepaper. I highly suggest that you do, for your future investments.
Its not wise to put your money into something you know nothing about, otherwise you're just gambling (and that
often ends up like Bitconnect)
Essentia is a good product, though, so if you invested you got lucky this time
