If you don't have any money to invest in bitcoin, it is better that you find a job and use part of your discretionary income to invest to enable you hodli your investment for long. Taking loan because you want to invest in bitcoin is a wrong approach and that alone can make your financial situation worst. This is because you will not have rest of mind and there will be emotional trauma most times. Whenever bitcoin price dips, you will almost have a heart attack. Lastly, bitcoin is not guaranteed to be profitable in future so we should not use past event to conclude what will happen in the future.
It is not even advisable for a manual labourer who is just a bricklayer to invest in bitcoin unless the person is working in warehouse, manufacturing companies or construction companies because those companies salary is high and he can do the mathematics to divide the salary into parts and invest in bitcoin with 1%. And using the DCA method to invest weekly or monthly all depends on the salary schedule.
I think you are wrong in this case, everyone can invest, even if they are construction workers, because I am a housewife, I can invest in Bitcoin and other crypto by just setting aside my spending money.
Everyone can invest if they have the intention and have a goal
Yes, its for everyone and it would really bej ust that wrong that you would really be making out those kind of limiting conditions about on whose the one would really be tending to invest.
We do know that as long you would really be that having the money to invest on then you could freely make out some decisions whether you would really be investing or not.
It all matters on how you would really be able to take the risks since not all would really be that able to bare up with the risks and would really be that much preferring
that they would really be wanting or liking on playing safe.
