So I checked some few details with Mina project here.
https://cryptorank.io/ico/mina-protocolDuring their seed round, they sold per Mina at $0.07 while their pre-sale price was sold at $0.15.
Now, they will be doing community sale priced at $0.25.
Though they will be unlocking over the period of 18 months. Still if you are a buyer of this upcoming comm sale, you need to be careful as the earliest buyers bought it at a cheap price.
They can even sell it at $0.20 and still earn profit. But if you do believe the potential of Mina, why not?
As the OP stated, he already did his research. So you already know what you are up to here.
And by the way, browse their wp, and it is a very technical one. So they really did put their effort into this project.
ECO, also is somewhat promising if you are talking about this project -

Most good ICO projects before were also abandoned after raising high amount of money.
