Let's say if you deposit the money into a bank and the annual interst rate is 3%, you will get a steady interest income year by year. If you use this money to buy Bitcoin, let's say the BTC drops to $17,000, you'll buy less than 6 Bitcoins. In the long run, what would you do with this money ? And why ?
Deposit is also kind of investment hence now you need to think about how much risk you are afford to do. If I were you, definitely I will choose bitcoin for all my money (by ignoring the diversification principle of investments). I may sound like over confident about bitcoin but for someone who is into this crypto space for more than a decade and able to predict the market direction within the cycles of bitcoin market, I guess there would be no other option might seem attractive.
Bitcoin can be your deposit and it would definitely will yield good returns. You may divide your into 5 parts and may consider five different investment opportunities including bank deposits and bitcoins.
I will do the same thing if I'll have such an amount of money. Depositing your funds in a bank is never a wrong decision but investing it in Bitcoin for me is also a better idea. Since I've known Bitcoin for a long time, I know how it could strike high so through long-term investment you could have a high profit and you can maximize your gains easily. It will take time but it's all worth it unlike in banks where you could only get a small percentage of profit after the long wait. But it all depends on your target profit. If you want assurance with lower risk and not aiming for huge profit, you can deposit at least half of your funds in your trusted bank.
