I completely agree that crypto will be the currency of the future. Cryptocurrencies are already used all over the world and constantly more and more countries begin to legalize cryptocurrencies and recognize them as official currencies, this is just a matter of time when the whole world will already fully begin to use cryptocurrencies with its full potential.
True it is just a matter of time but yet more advancement or improvements is still needed, and most importantly lesser or no scam projects, because this issue of scam projects tends to drag the crypto space behind. However, when studying the crypto space it is clear that Crypto will have a say in the future because it tends to offer more better alternative to fiat in certain cases. Lastly, not all crypto will make it to the future, in fact only few will be able to pitch their tents hence whatever anyone is doing or investing in any crypto for long term, let due diligence be done first.
