In terms of price stability, cryptocurrencies can be divided into two major categories — volatile coins and stable coins. Cryptocurrencies like Bitcoin and ETH are highly volatile as their prices keep changing very frequently. On the other hand, the price of cryptocurrencies like Titan coin and Tether is relatively stable.
Because the price of stablecoins remains constant and stable, they are preferred for long-term investment. One can earn significant returns by HODLing stablecoins for some time. Also, there are some platforms that offer an interest on stablecoins.
I believe DAI is the best one until something wrong goes belly up there. All the other ones I know of is tied to a company, busd is binance, usdc is circle I think, gusd is winklevoss twins if I am not wrong, and usdt is the biggest one we know and that is tether as we all know.
I do not like it when other companies have their own coins, this is valid for xrp as well because it is tied to ripple company. Whenever there is a company behind something I am not really fine with that and I think it should not exist, we should all have decentralized currencies that is not tied to anything.
DAI is like that, it is a decentralized one that is not tied to anyone or any company and that is why I think that one is the best one by far. I hope that one day everyone realizes this, sells their usdt so that we do not have all our money tied with just one company that could steal it.
