Yes that is true, because Fiat money is not always good, it will continue to decline because inflation always happens, so this is very detrimental, but if we invest in Crypto like Bitcoin and Ethereum, we will get opportunities at very high prices to increase.
Some of them are and some of them are not according to me this is good to invest only in the crypto currency like bitcoin and ETH because it has high scope and it has great demand in market. Gradually and slowly we are moving towards digital age where all this will be need of life so better to start using crypto instead of paper money now.
