what is the another ways to lifted up the Value of bitcoins in the market?
The bitcoin price is down currently because there is a correction going on in the market. Maybe in a month or two the bitcoin price will start moving upwards.
Also there are no new retail investors - if you check out Google Trends the term "bitcoin" is well down on where it was in June. A lot more work needs to go into marketing bitcoin as a currency and an asset before we see retail investors come back into the cryptocurrency space.
