Bitcoin investment compared to other investment can make newbies who have the zeal of investing in bitcoin lose interest.It also increase fear of loss and indecision in bitcoin investment.So on the contrary, bitcoin should not be compared to other investment because bitcoin investment is a decentralized investment that is best for long term(hodling)with the belief that the price will go to the moon.
A person who invests in Bitcoin will never worry about the price. Because the DCA method of investing allows you to invest in any position at any time, as it controls the average of the Bitcoin price.
That's why I think the DCA method is the best, but the time limit for Bitcoin investment should be at least 10 to 12 years. Bitcoin will reach its peak after 2030, and you will be the participant who will benefit from the most investment.
