as far as I think investing in bitcoin and bank are equally good, but for me it's still nice to save money in bitcoin than we keep it in the bank, because the opinion of the dibank is very low compared to bitcoin.
actually both equally need each other and fill each other with the advantages and disadvantages of each, but the matter of investment of course very clear it is better with bitcoin than with a high enough price and the need with bitcoin is very high, but the impact is also very big if you lose compared with banks certainly safer and fewer losses.
