Investing a reasonable amount with close monitoring of the system. Knowing when to continue pulling the gear and when to call it a halt.
I would say that cryptocurrency is not meant for everyone. If you don’t have enough money to invest, then its best to stay out of it, cause it won’t work. If you decide to invest all you have because you believe that you would be lucky to make profit within a short time then you are making a big mistake. It doesn’t work like that. You first make sure that you have enough money before you think investing like 1 – 5% of your money.
Nobody can give a perfect answer to OP for such a question. This is all about how will bitcoin perform in near future but for an end user, it is all about luck which doesn’t work all the time. So saying that you’re buying bitcoin with as much money as you have is wrong, you just have to invest little of what you have, so that you wouldn’t have to regret if loss occurs.
