The price will be able to rise up higher but it will not be like last year However The ETF accepted will increase all investors' and users' failth and this fact will lead to bigger extension of bitcoin . After that bitcoin is possibly considered as future assets .
Do not be so sure yet, so many people said the same thing when the CME and CBOE futures contract was going to be launched and I saw a lot of people even calling $1m.
ETF or no ETF, the market has been growing and nothing will change the fact that even without it, the market would still not continue with its steady growth over the years as well as development, so I really do not see much effect even if there is any at all when it comes to ETF being approved.
We should focus more on seeing real life usage, than just assuming that ETF approval will just save the day for people who are looking to acquire wealth in the short term. Institutions are not dumb, they will get the weak hands out of the way to gain a better position in the long run.
