Your friend must be fortunate or wise enough to initially consider changing his altcoins to bitcoin. Not everyone who has invested in altcoins benefits from them. Altcoin investment is mostly good for a short-term investment plan not for a long-term goal. Once there are profits in it, you sell it off to avoid losses.
That's what I think your friend learned about altcoin investments, which prompted him to swiftly change them to bitcoin to secure his profits and increase his chances of long-term gains.
It always makes sense to exchange altcoins for bitcoin, and if it is for long-term investing, or to try to trade altcoins in pair with bitcoin in order to increase the number of satoshis on the balance. But in the end, even if you trade altcoins, you should strive to eventually convert everything into bitcoin, the main goal should always be to increase the amount of bitcoin in the wallet.
You could do vice versa but if your heart and mind telling you that you should only focus with bitcoin then do it and do things as much as you could when it comes to methods and ways on which you would really be able to make that advantage when it comes to accumulation of Bitcoin.Yes, there would be sacrifices and other steps that you would make to be able to reach out this kind of goal.
Not all would really be financially capable on doing so and this is why we do really have different situations when it comes to profitability.Some would just simply ignore and some wont really just care but there would be people who would really be doing into things basing up on what they have researched or have seen on.
Limit out and doesnt mind about on the future will really be putting up you on a condition that you would really be getting left behind into those people who had made out such
step for them have those good results in the future but of course, everything isnt really that assured or guaranteed.
