Testnets and some mainnet activities are a good way to familiarize yourself with projects and get a deeper understanding of the crypto industry. I participate in a few of them too. And so far I can conclude that I got more joy from the fact that I once decided not to participate in most of these projects, as such giveaways that organize most crypto projects can be called a disgrace and total disrespect to the community. I don't want to be a nerd and write only negativity, but so far there is little good here and the worst scenarios are confirmed, that the crypto industry is simply being mastered by bankers and corporations as a platform for dumping excessive fiat money. This means that bubbles similar to stock market bubbles will be inflated, which is facilitated in no small part by the so-called decentralization and lack of regulation. Since no one is responsible for anything (to the users, of course), this is a very favorable environment for fraud.
