I don't see anything wrong with what you did. If you are really interested in Bitcoin or cryptocurrency, buying a laptop is part of the investment too. Now, if you used bitcoin to buy a laptop, I don't see anything wrong with it either.
Because you have knowledge of Bitcoin or crypto, it can also give you profit in the future, so just continue the research or study you have started here in the business field of the crypto industry.
Exactly, I don't understand what is wrong with selling your bitcoin to buy a laptop because people invest in bitcoin to make money to solve their problems and needs, and you sold bitcoin to buy a laptop because he will help you and do many things on the internet and do more research about investment, so just find another fund to replace the money you touched from bitcoin to buy laptops and invest on it again, because I am confident you will continue to make money so never regret on bitcoin, Because investing in bitcoin at any time is the best option because the price can rise at any time, so invest in it now and leave it for the long term, because it is the finest investment for now that you will not have any problems with.
I believe the odd feeling of always keeping your Bitcoin and not selling it forever is for those who are ardent about it, they are becoming an extremist to the level of depriving themselves and getting to hold and own it forever. But it should not be like that. It's already a privilege that you know Bitcoin as a means to invest, and just like any other asset, it's for investments so as to make more money, not something you should worship or keep forever. What if something else which is negative happens later in the future? You would have deprived yourself of the money you invested, the gains and what you should have done with some of the gains. This is why no one should always believe in any asset 100% and if the asset had already given you a tangible amount which you could use some of it for other personal needs, why not use it?
The reason for investment is for a better life and financial freedom, so why still deprive yourself if you have the money through the Bitcoin investment? And if the guy removed some of the profits, this still doesn't mean that he will not continue to invest more money in his Bitcoin as he later has. However, at that time, the pressing needs have to be tackled especially if the need is what is worth it, like buying a laptop and others as you mentioned. For me, buying a laptop is even better and worth it more because I use it for my work which earns me money, so why deprive myself and believe I can only earn money through Bitcoin? That's the way I see it.
Bitcoin is an investment, we should always treat it as such and not more, and we should keep on pumping it if there are excesses.
