Of course, investing in BTC is a much better idea. The incomes in banks are extremely low and require to keep your money the whole year to earn 10-18-20% of income. Cryptocurrencies are very volatile and they can bring 10-20% profit in just a day like we experienced lately. Therefore, you can double your investments several times in cryptos but only if you know how this market works. Do not invest in Bitcoin if you don't know a thing about it and crypto-market, at least use advice or help of professional experienced traders.
The best way to enter this market, in my opinion, is to wait for a huge correction that lasts approximately a week and buy BTC when the price stops falling. This way you can wait for a good profit in the nearest week or month.

Investment on bitcoin and bank have different advantages and disadvantages. In bitcoin, you will earn big profit when you're patience on waiting for its price to increase, but its not guaranteed that your investments is safe. In bank, you will just earn minimal profit, but you're sure that your investments is safe. I suggest to do both for you to not be bankrupt when something bad happens.

I invest bitcoin instead of bank deposit...now bitcoin price is so low and I should invest heavily and it's bring me huge profits.

Of course, it is more reliable to keep money in the bank than to invest in the crypto currency. However, the percentage of payments in banks is minimal.

Tell him that investing bitcoin is better than bank, its because you can control your own money. You can get a higher profit with a short period of time. You can double your investment in bitcoin so easily. Well it depends on you , if you have enough knowledge in bitcoin then its easy for you to invest.

If I will be asked whether I will invest in bitcoin or bank I prefer to invest in bitcoin because of it's higher returned rather than in the bank the interest is just a little and has a tax.  So bitcoin is better investment than investing in the bank with lower return.

Just split your investment. Diversify.

I think its up to you largely to determine whether you would want t go ahead with the plan to either invest your money in the bank or in crypto, however as a word of advice not taking any risk is risky itself and taking miscalculated risks is equally very risky so do your findings well before you jump in. better safe than sorry

If I will be given a chance I would rather go to invest than banks, cause in banks you are not going to take your money within the contract, and I guess that's what it must be better save in bank than to invest dinxe the increase of your money will just be like 1% and it's annually , juat like that here in bitcoin it may be a risky thing but it is sure to be a big one.
