I think that the first thing to build a crypto hedge fund is to be a solid trader, move from 1k to 1-2M, THEN raise few funds, THEN get the support and tech, THEN raise big... If you don't get reputation in the market nobody will give you money. Majority of traders start small, and as you pointed out the mentality is really different form size to size, the owner of the fund should be at the highest stage in order to convince people to invest.
