Sure, I'll speak to cryptocurrency and tokens that run on blockchain, since it's the technology that made the wide spread of crypto possible.

As an aside, I've been out of this sector for a few years now. I'm behind on recent developments. And, I was never a programmer or developer, I worked more on the writing and art side. In depth tech analysis will have to be directed to someone more knowledgeable than me.

I have a lot of criticism for blockchain and cryptocurrency as well, so don't take this as a vehement defence of the technology. I'm only answering the question with a few points.

1. Decentralization of currency — reduces the monopoly on currency. Yes, a lack of regulation has done some serious damage, but that's an issue with clunky legislation not keeping up with technology. The point still stands that centralized control of currency, or anything, also centralizes power, which is susceptible to corruption. Blockchain isn't the best solution, but it is an option.

2. International money transfers are easier on blockchain. One company I worked for paid remote contractors in cryptocurrency when dealing with foreign banks, who often didn't speak the same language, in less developed countries (Including America, hah.) Quite a few countries have integrated crypto into their banks which made it more practical and cheaper — they actually preferred it.

3. Digitial trust. The distributed ledger, though inefficient, created a strong, secure system that is prohibitively costly to corrupt. It's easier to play the game than to cheat, even if the whales are in it.

4. Personal, international trade. On a personal note, I was able to post and sell my art internationally without messing around with foreign money transfers. If you've ever had to send money to someone in the states from Canada, you know what I mean. A transfer took seconds and the distributed ledger made it so there would be no backsies or disputes.

5. NFTs... you're all gonna hate me here. I accept it, because NFT hype was crazy pants — BUT! It was like selling art prints digitally. I included a creative commons contract that was folded and sealed into the blockchain and high quality images that could be printed anywhere in the world, instead of shipping the prints themselves. Blockchain just made it easy to set up and manage on my own. Otherwise, to sell internationally I would have had to use Etsy or something. With a little know-how I could forge and trade NFTs directly and it cost only pennies to transfer.

6. I can buy stuff with crypto, directly. There are lots of companies who take it, including the print shop who does my stickers.

Now, these points aren't exclusive to blockchain. There are quite a few options out there to handle the various problems blockchain solves, but I have yet to find an easier way to transfer funds internationally than by using blockchain based crypto.
