I believe that factors that may help BTC to rise or gain more income is to people must be patience in waiting for the value to goes high. People must help one another in order for them to gain higher income than they expected. Also, people must be wise so that hackers will not easily get or scam their account.
There is only one factor and that is investment capital for the growth in price. I think that the price will never go up until the demand for it will not increase. Now people understand what crypto is better for investment and how much they need to buy some Altcoin. The price with bitcoin is that it is very expensive and small investors keep aside from bitcoin.
