So, next time when someone tells you that Crypto currencies are used for scams, please highlight the fact that most scams are still being done under the nose of the regulated financial industry.
I find the last line very amusing as most people ignore the fact that even highly-regulated investment methods and financial trades are prone to scams!
Unfortunately, cryptocurrencies have been branded heavily and portrayed in the media as a 'scam' due to its volatility as the price may be controlled by the law of demand and supply. These people who complain about bitcoin being a sketchy scheme are also the ones who impulsively invested in bitcoin and LOST due to something independent from their actions. They failed to study the market and so, join the bandwagon and blame about its existence.
Undeniably, bitcoin has already created tons of millionaires and inspired many to reach their dreams of owning their business, etc.
