Avoid ending up like a friend, who used all the money he has to invest in bitcoin and also took a loan, promising the lender that he will pay back when he gets paid in a month, after a month he never received the salary, I warned him doing this, because he has no doubt mixed investment with 'whatever it takes', is it safe to call this greed? I don't know.
Now he wants me to lend him some money to at least pay the loaner back and later settle me, there is more, now I have to send him some money to buy some food.
You don't have to use all your money to invest, even if you are not married yet or have other responsibilities, the best approach when planning to invest in Bitcoin is to buy with some percentage of the money you earning, maybe through business or a job.
If you do this weekly or monthly you won't feel any pressure, always remember that health is wealth.
Investing needs not to be rushed but it takes a good plan before you will start doing it. And when you do, its best to invest at a spare money or from your own savings that you can manage to lose, not from a loan amount or money that is reserved to pay the bills. Because we all know that bitcoin investing is for long term, so we should not expect quick profits from it, the reason why we should only invest with extra money that we are not going to use.
