If an investor has a good source of income and if he plans to invest consistently while having a good source of income then I think that investor will be successful with his investment plan. But an important factor that will work in this case is how much money the investor is consistently investing.
No, the investor can be successful even if s/he has all the funds to invest consistently while s/he lacks the important factor which is understanding how the market works, and how to secure the Bitcoin s/he invested in.
Everything is not about having the funds.
Although it is a bit late to start investing, I would say that before starting investment, you should start investing with a proper plan. I think it would be a better move for any investor to start investing with some time and stay with that investment rather than selling the investment mid-way through the investment.
There's nothing been late to start investing in Bitcoin since the 21 million total coin is yet to be mine. You said it yourself, the person needs a proper investment plan that will make him/her hold the BTC for the long term.
I don’t see reason that beginners need to study about the Bitcoin market before they start their bitcoin investment journey ,It is not necessary to study any market. All beginners need is basic knowledge of buying Bitcoin and the best wallet they can use to store their Bitcoin.
A beginner to bitcoin does not need to learn about bitcoin wallets before starting to invest into bitcoin.
SOKO-DEKE There's nothing bad for beginners learning about the Bitcoin market (particularly the 4-year cycle which will give them more understanding about BTC inflation control, and volatility).
JayJuanGee They don't need to learn about how to use a wallet before investing in Bitcoin but what will happen if they lack the knowledge on how they will keep their BTC safe when we're in the season where it is more important for people to hold their BTC in self-custodial wallets?
