My guess is yes. Simply supply and demand metrics in my eyes will keep bitcoin up...
Increasing forever is not the right term I guess. There will be some ups and downs but the chart tells us that bitcoin will keep on increasing. Determining the supply and demand of bitcoin today it simply says that there's a big market for it and still many people aren't getting in the league and for sure when they started to hop in to bitcoin they'll be helping to make the price higher. As of today, the crypto market cap is totally high and there's a chance that 1/4 of the increase or higher from other altcoins can go to bitcoin within the next years.
Bitcoins popularity is increasing day by day through various channels that's why many new investors are coming day by day to invest in Bitcoin. Demand is increasing daily but supply is Limited and it is increasing the price of Bitcoin.
Yes there are rumors in the market that big investors get out of the race anytime and it will result in breakdown of the price but in my views it will not happen.
