Various things are at play here. While ignorance is the genesis of every controversies surrounding crypto, experience also form part of it and you won't blame people for calling crypto a scam if they once fall victim to scammers. One problem we are having is that we prioritise money over knowledge this days since those that have it have control over others. People rather risk their hard earned money to make more money instead of taking out their time to learn and relearn.

In the process of being eager to make this money from whatever way possible, many have fallen victim to scammers in crypto space either by investing or pump and dump coins or some crypto investments platforms that offers them high returns. Anyone who fall for this trap will be quick to tag crypto as a scam. Some of them will later change their view about it when they later realise they were swimming in ignorance before but others will remain adamant with what they initially believed either because they don't longer have interest or they don't care to seek knowledge.
