Crypto is not used to bypass regulations.

From the very beginning it was sold as a way to work outside the existing banking system and all it did was recreate the earlier days of banking with little-to-no regulation.

It is easier to regulate crypto because of the public multiple ledger system that is the Blockchain, allowing you to trace tokens all the way back to their conception.

The key to regulation is enforcement. While some regulation was put on the books, the government has been very lax with enforcement. Obvious pump and dump schemes, which would be illegal with securities, are left completely alone with crypto. Ridiculous amounts of leverage has been used to pump up the value of bitcoin, including fraudulent printing (see Tether). Also, while the bitcoin ledger is public, you can shuffle and obscure entry and exit points enough to make it anonymous.

The purpose of Crypto is that it removes the need for a bank for transactions and holding of nonphysical currency. Adoption rate proportional to total population is what gives them stability and makes them less susceptible to scams or pump and dumps.

It removes the bank and introduces mining consensus. In the case of bitcoin, this consensus is slow and costly so people have built more centralized networks on top of it. Those are your new banks right there. Plus there is the issue of mining pools becoming too large and thus having more say in the consensus. Now talk about Proof of Stake and you’ll find it’s just a system where the more you hold, the more power you have (i.e. like the rich who hold more money).
