I really believe in XLM, but I have no idea about Dero. If I had to choose between the two, I'd pick XLM. I think it still has potential and I've seen that even now,
it hasn't fallen behind the top altcoins in the crypto space.
In fact, it's one of the coins I hold for the long term, just a small amount, and I plan to hold onto it for a while. That's all I'm doing with it for now,
even though it's not my top priority to accumulate a lot of it.
XLM is not something you should have any trust in, anything that is trying to copy and do a "better" version is already at the wrong path, because XLM isn't good enough to copy to start off with, and itself is not that great. What did you see from stellar that made anyone think that they should invest into it?
There hasn't been anything that is reasonably good enough and because of this we should avoid it. Too many people end up with results that are not that great, and because of that we are not going to get the best results out of this. Of course things aren't always that complicated when given enough time, but XLM had it's time, and it didn't get the attention or love from the public, enough to make it a big coin.
