We have a bit of everything in that sense, I worked in an excel combining pieces of information from multiple sides (DAO maker and coin tracking, mainly) and grossly the stats are the following:
a) Invested in presales: 38.900$
b) Realized profit: 57.843$
Net amount (b-a) = 18.943$ (this is pure profit already realized).
c) value in USD of vested tokens: 33.023$
This (c) means that if all the locked tokens were unlocked today, the extractable value would be around 33K$ more which added to the realized profit would sum a bit more than 90K$.
So yes, we can conclude that DAO Maker presales are very profitable (even more if we account for the fact that the majors are overall -70% down and shitcoins -90% minimum).
I'll try to write a more detailed article with this information soon, but you get the point :)
Cheers!
