I think there will only be indirect impact that the huge stimulus package will cause to Bitcoin. The direct impact will be felt by fiat itself, its value in particular. With the fast printing of money out of thin air, the supply is fast growing. As a result, the purchasing power of fiat will sorely decrease. The inflation rate will rise beyond the tolerable level. This is basically a slow suicide on the part of fiat. Consequently, Bitcoin, as an alternative to fiat, will become more attractive, I suppose.
