Now that it is clear that one needs to have an idea of the business he or she wants to invest in, that's why l keep asking if someone can invest in bitcoin even when you don't have an idea of how it works?
i understand what you mean though, but one thing you should know is that bitcoin investment is not like other form of business that requires you to do a lot of market survey before embanking on it. in bitcoin you only need basic knowledge to buy from exchange and stack it on your non custodial wallet for long term use, that is if you are an investor. except you are a trader that you will need a lot of study to learn the skill in trading to be profitable in a short time. so someone who doesn't know much about bitcoin can invest. not that they will completely not know anything at all, but will be aware about the basic things they need to know for a startup.
Definitely, cause someone who has zero idea about Bitcoin has none of it so since they've missed the opportunity of buying it earlier it's best to learn the basics and start accumulating instead of waiting to learn it all and continue to miss out on buying it cheaper, the market is volatile and you never can tell what the price would be at different Intervals.
That's why investing in Bitcoin is more better than other crypto related financial opportunities cause it's easy to learn and understand, unlike trading that would require one to constantly monitor the market, analyse and master the act of buying, selling and calculating stop loss, all those are not required for investing in Bitcoin, with the basic knowledge and discretionary funds intact, a newbie investor is okay.
