Bitcoin is definitely not one I would sink a lot of speculative money into. It is the oldest tech, which means it has a lot of people in on it, and name recognition, but it also functionally doesn’t work great, compared to others.
Etherium is a bit better, newer, tied to a lot of NFT stuff, so there is some functionality there, and they have committed (though moved the deadline many times) to moving their currency to proof of stake, which would vastly reduce the amount of carbon emissions it is generating mining. But it is also older tech.
Solana, I like, because it has one of the fastest and cheapest transaction times, making it the “visa” of the crypto world. Which to me, at least, seems like a function money should have. You know, quick transaction times. Not hours or even days for some crypto. Solana is also backing some real world big company transactions.
Cardano is fairly similar to Solana, in terms of speed of transactions, as well as proof of stake. They also have set up the coin so that holders of the coin receive dividends (like a stock). Making it a passive income source.
That is about all I know. I certainly wouldn’t drop tons of money into crypto, but if you want to hedge your bets, I guess now would be a good time. It is a big dip right now.
I honestly ended up buying more crypto after I watched the “line goes up” video, because it stressed to me how crappy this all is, and how it is quite possible that we will be forced into a decentralized currency future. I would rather be safe and spend a bunch of “throwaway” money just in case that becomes true.
Again, I cannot stress this enough, I only put in money I was willing to lose. It is like going to Vegas. We will see where the accounts are at in 5 years.
