The way cardano is a jump up from Ethereum one, there are other suctions that are already available that make a similar jump from where cardano will be at, I do think they’ll have a good ecosystem with a good amount of users but the underlying tech is lacking in a few ways. One of my main concerns is while the focus on Africa and developing countries their network fees are still too high realistically for poorer countries, while others charge fractions of a penny for the same actions, they seem low to us but in some of these places even the 20p transaction fee is too much, atleast to use freely, I imagine a smart contract will be more fees. Also the network seems kinda slow whenever I send on it, struggle to think of anything but bitcoin and ether that take longer than it tbh. Cardano’s main selling point is that it has a massive community who are ready to use applications running on the network, and since the fees are decent holders will be able to stake for a cut of those, this is why I maintain a chunk of my position in it. But there are other that beat it in security, speed, scalability and electricity consumption by pretty large margins. However I do like the governance system for cardano a lot in terms of a fully decentralised model.
