The crypto market has a high level of volatility. Anyone who is about to make an investment needs to have a good understanding of the volatile market. Now the question is, even with volatility, will you still choose to make your investment in fiat through bank savings with regular monthly interests or rather make your investments in crypto where you hold your asset and still have the opportunity to save and make monthly interest?
I have always stored millions in the bank since 10 years ago now and I can tell you that you won't make anything worth talking about leaving your money in the bank account, the truth that many people don't know is that those banks are also big investors too, they have access to peoples fund right? They can take them money out and invest in other things using money that doesn't belong to the bank.
They will make great income and you ain't going to get a dime out of it, this is what SBF did but he isn't running a bank anyway and he took things too far, I am not surprised that they fought so hard to bring him down because it's crypto exchange anyway, not a bank, if it's a bank we might never heard all about this but the war was on crypto in general.
I would rather have all my money in crypto and stocks, when Bitcoin makes a new all time high I will take some profits, even if it's just a 2x of my initial investment it's still something that the banks can't give you if you storing your funds in your bank account.
Putting money in a bank is actually a bad idea if what we want is profit or to store the value of our assets. Bitcoin or stocks, assets like gold, real estate would be a much better choice. But putting all your money into bitcoin or stocks is also not a wise decision. You need to think about life's emergencies and what happens if you're in bear season, or the value of your portfolio is losing money. No matter what you say, in life we will still need fiat and banks, but we should not put all our assets into it, just enough, the rest should be invested in bitcoin.
