My experience:
There's a high level of security. Crypto currencies are not always affected by inflation in the market and very volatile in nature. The convenience of trading at anytime and the easy made of crypto currency liquidity across multiple exchanges. There's equality and fairness on either sides of the market. It's always a win-win situation whether you're buying or selling if you know what you're doing. And there's also a high level of transaction freedom.
BTC is deflationary, and it is secure because of the high hash rate, consensus mechanism, decentralization etc. But with self-custody it is only as safe as you make it, if you are not up for the responsibilty of self-custody, it is better to stay with paper money, it is even worse for bitcoiners who don't practice self-custody, that is bitcoiners who use custodial wallets and services; they bear more risks that the average user of fiat centralized services.
You are alluding to crypto and not BTC, so you better be careful trading shitcoins in centralized exchanges, it may be convenient until it is not. BTC is a 'community network' so we could talk about 'equality' and 'fairness' you mentioned, but again you generalized it as crypto, maybe you should know that many crypto's are centralized and controlled by a small group, like ETH that just moved to POS that allows for centralization and the possibility of powerful staking pools and censoring of transactions, in BTC POW it is impossible for a miner to control 51% of the hash rate.
It can only be a win-win for a crypto user if they use the right coin (BTC) and have the knowledge they need about it.
