I think many of the cryptocurrencies are simply just tokens and have no point of having their own chain.

I like smat contracts and think of them as blockchain 2.0. I don't see them as replacing money, I see them as replacing contracts and more. They are too complicated to replace money. Neo, Tron, Bnb, Eos seem too similar to ethereum to comment on. For the most part they are just more centralized and tweaked slightly in terms of voting or whatever. Xlm I want to throw in this category, but it's quite unique and not as smart as the others.

Xrp i want to classify as similar to libra but not pegged, I actually see huge potential with this type of token for replacing money as we know it. Nano, Steem and xlm somewhat fall into this category as well.

Then we have privacy coins which are great, but I don't see a huge future there. Everytime we have mainstream criticism, guess what I think about how monero will keep crypto dodgy.

LTC was my second love after btc. I'm not currently heavily in it, but I did really well. I think it's good to keep around and better than the forks like bch and bsv which seem like outright cash grabs.

The decentralized coins, I don't know mich about these actually, but I've used DEX before and like the concept of idex l, and 0x or whatever it is. I'm not currently speculating on those. I want to see ibm nasdaq or stellar launch somethig more traditional first.

Bottom line, we need adoption. I guess i have research left like iota and ada, they are great, but I'll leave the btc millionaire's and developers to that.
