I disagree that you put all of your savings to cryptocurrency because indeed the price here are very volatile it might change immediately. We are giving our opinions here but the final decisions is yours.
It's volatile but we can't stop those people that are fully trusting in bitcoin or any altcoin of their choice.
I doubt it that they will just invest it without further notice on what they are going to do or didn't have any research before doing it.
It's either they don't want to deposit it to the bank and earn a little interest so instead of putting it there, converting it to crypto is way profitable than it.
I think that investing savings into anything is very risky, but where is risk there is a huge
profit. I decided to take that risk and for months I invest in crypto-currencies and that is my
saving. I did not have big savings before cause of that I invested end ever I had chance for
that.
For now I am very satisfied and I know that investing savings s far more riskier than investing
little by little, but take a look on history who invested until now did not make a mistake. Do not
risk if you can not handle it, but without risk for what we can hope?
You had to understand that in the first place, there's a risk that's associated with any type of investment and it's even riskier if you'll do it without enough knowledge.
I don't have big savings too and the interest that I can get in saving my money in the bank is not that high or by just letting my savings on my vault, there's no movement too.
It's good that we have our own investments, whether it's with altcoins or bitcoin only.
I believe you will do well and could retire with this eventually
