...If I don't like overhyped discussions so I just tell them it is far better compared to having their money saved in the bank for 1 year doing nothing I do this to avoid been held by my words if things goes wrong...
There is no doubt that investing in bitcoin will be much more profitable than keeping your money in the bank. Given the dynamics of the cryptocurrency market, the profit in this case can reach several hundred percent. But this will only be true if the market is bullish. Otherwise, 1-2% in the bank may be higher than you will earn on holding bitcoin.
Bank has lower risk but lower profit; bitcoin has high risk but high reward. You must decide wisely what risk you will take; will you play it safe? then go to the bank and make a time deposit, but if you are a risk taker, then invest in bitcoin, but first gain knowledge yourself so that you are not surprised by bitcoin. Risking huge money now is difficult, which is why some investors will invest in other assests. But those who really want to take a risk will invest in bitcoin, but they will conduct research first to lessen the risk, and they have plans. This applies to all investments; you can lessen the risk if you have plans.
