Some people think that bitcoin is a scam as a result of their frequent encounters with fraudulent activities using bitcoin, and sometimes, bitcoin platforms. No matter how genuine bitcoin as a currency is, frequent encounters of scam with it or its platforms can change people's mind to consider it as a total scam without distinguishing between bitcoin and scam, but that is not appropriate. For example, for the fact that pound or dollar is a genuine currency, does not mean that scammers can not use them for scam, likewise bitcoin.
I that was at the earliest time when people do not understand what Bitcoin really means and how to keep there Bitcoin safer. For those that had been holding Bitcoin for a long time now, they know how the market works and the best time to buy and hold Bitcoin because they had been in the market for many years. The misinformation people had then about Bitcoin are now been clarified when they see cryptocurrency investors and those that only invest in just ordinary fiat market or non cryptocurrency platform. The result is very clear and it is not something we need to compare at all.
