The fact is that no one can predict the further development of events in the cryptocurrency market with a 100% guarantee of success.  We will still observe not only ups, but also a drop in prices for Bitcoin, and therefore we do not need to fully focus our attention only on income from the cryptocurrency market.  No need to take loans to buy Bitcoin, because the risks are very big.  But I believe that Bitcoin can cope with its problems if the scalability problem is solved first, but at the moment it is impossible to do this in my opinion.
