It is not late to invest, the price of the market is still fair to buy to invest. But since he is not very experienced investing it will be better for him to invest with the amount he can afford to loses. Bitcoin is the most reliable coin for inexperienced people to start with for investment. It is not advisable for beginners who are not familiar with the market to consider investing altcoins as a good investment because the risk involved investing altcoins is high. It is better to stick to bitcoin and get more experience before thinking of investing in other coins.
Bitcoin has been around
for decades, and I'm convinced it's here to stay. In comparison to the others, it feels more like an autonomous initiative that coincides with bear season. It has never been too late to begin; fresh opportunities await each of us, and it is our responsibility to make the best possible use of our opportunities. Furthermore, there are numerous groups of newbies who were acquainted with the area this year, and they have significant entries on bitcoin and invested in other potential projects. The space is all about gathering legitimate knowledge and backing it up with continued research.
Well, not decades but more than a decade (we all know about it, but I clarify just in case any newbie is reading).
About the fact that it has never been too late to begin, it is true that the pattern has always repeated and it seems that it will repeat again next year, but don't forget that people who bought the top in 2021 are under water now and still have to get more than half of his money back.
On the other hand, it is also true that it is almost impossible to repeat the gains from previous phases and it would be unreasonable to think that two pizzas bought today will be worth several hundred million dollars in 10 years, for example (because the market cap should go nuts for that, defying any market logic).
So I don't think that it is too late to start if you only plan to get decent gains, higher than the ones you'd get in tradicional markets (in exchange of higher risk, nothing is free in this life), but I also think that it is too late in the case someone expects to retire early for having invested just a few bucks now.
