The last time I checked, bitcoin investment is very easy to start and not complicated and challenging to handle. Bitcoin investment can only be complicated and challenging to handle when you use the money that is meant to sort out your daily expenses and invest in bitcoin because at some point you will struggle to solve your daily expenses, which might cause you to sell your bitcoin even though you are at a loss to survive and get your daily expenses sorted out. But if you figure out you will have discretionary income and invest in bitcoin within your discretionary income, you will always find it easy to invest in bitcoin, which will allow you to hold your bitcoin for the long term because you will always be in the position of solving your daily expenses at any time they arise.
You are right anyone can invest in Bitcoin as long as they have a good understanding of how Bitcoin works and regarding the funds that will be used to invest in Bitcoin of course they must first settle their daily needs in order to run the investment properly and achieve the targets they set for themselves, as you said it is very true if someone is not able to meet their daily needs properly then it will be difficult to maintain the investment until the targets they set are achieved.
It is very important before deciding to invest in Bitcoin or anything else, we must first fulfill our daily needs and also have funds ready to invest without being disturbed by our needs.
