Actually holding bitcoin will for surely help the ecosystem of it. The price of it is probably gonna rise up since it will lessen the supply in the market. The lower the supply, the higher chance that the price will rise up also. As long as the demand is higher than the supply, the price of it will become higher and higher every single day.
But that doesn't inherently mean anything positive other than superficial wealth increases that can also be lost just as fast as it is gained. I would much rather work towards having a functional currency even if it means replacing the block reward algo and total supply cap than to have "digital gold". Fiat is not going to last forever and Bitcoin is hardly a reasonable alternative in the event of a collapse.
