>>105930478 (OP)>start understandingLiterally all is a grift. Cryptocurrency can be good (XMR), NFTs got a point (digital ownership, not investment) but web3 simply isn't a thing and it can't be forced.
>contributing to Web3Impossible because see above
>contributing to decentralizedDecentralization was and is possible without web3. The easiest example of decentralization is torrenting which has already been available in the 90s.
>Exactly what should i learn?Focus on XMR if you desperately want to learn about cryptocurrencies. 'Breaking Monero' is pretty great. For decentralization learn about basic network infrastructure and how projects like Tor, I2P etc work, their pros and cons, if you wanna go far also the attacks possible on them and the ones that were performed.
>pythonIrrelevant for pretty much all tech products, especially anything that isn't a poc.
