I always saw BTC as enabling money laundering from questionable practices. Only in the last two years have I fully understood how it works and the benefits of blockchain and cryptocurrencies as a tool. Learning about new projects really opens your mind to the new possibilities of networking and communications, and there has been some very good solutions to the problems we face.
However, I do not like the current climate of the technologies being used as a stock market to make a quick buck, forcing governments to act. I fear this greed and usary will destroy the industry (probably intentional). I also do not like the idea of social media on the blockchain since we all say things we may not mean (or get misinterpreted) and our views change over time. Blockchain is forever and your post will never truly be deleted (maybe hidden). Enforcing anti-censorship laws seems like a better solution. Blockchain should be reserved for finances, voting, and archiving history, but it is quickly being implemented as a way to track everything we do say and think forever by governments.
A handful of smart contract projects should have a strong future going forward as will privacy coins (monero, zcash, piratechain). Media distribution platforms will come and go (hive, somee, bittorrent, theta). NFTs are a scam and game coins will never catch on. PoW is really great for decentralization and cannot be shut down by government, but it is extremely wasteful on energy and eventually institutions can take over mining. Most PoS ecosystems require top-end hardware, perfect network connection, and outrageous minimum balances to be a node, thus centralizing the transactions despite being delegatable. I see most projects as a temporary stock market based on artificial scarcity and a dream. In reality, all these projects are just unpaid research and beta tests for the NWOs UBI CBDCs... Remember, privacy is the future of blockchain.
That is my opinion.
