It’s bad that you didn’t return it a year and a half ago, since then the price was 20 thousand for Bitcoin. Now is not the best time to invest, because the price has long been in the corridor between 60-70k and sometimes breaks it up and down. If you decide to buy Bitcoin, it’s better not to do it now, but at the next drop to 60, or 57k. Because at least this way you can be sure that the price will continue to rise.
However, if you are here to accumulate and hold it for long term, buying at the present price is not actually a problem. After all, you wouldn't dare to sell at a loss price so even if you try to buy a small amount with the current price, this is still considered a good buy. But if you want to wait for a little pullback of price, that's also a wise decision. You can actually make bigger profits in the future if you started buying bitcoin at an affordable price.
If a person really has the commitment to become an investor and hold for the long term, then buying at the current price is not really a problem, not only because I at least expect the price of bitcoin to double at the end of this bull run, but also because even if it did not happened, bitcoin is still one of the best assets you can buy and this is not going to change, so investing in it right now is a great move that will eventually give you the profits you are looking for.
