I've seen altcoins adopt SegWit, ... and that's a good thing right?
If an altcoin adopts seqwit, then at least it is aiming somewhat in a possible better direction by making an effort to relate to bitcoin, but I frequently still would question the altcoin on other grounds, at least, minimally, in terms about why it needs it's own token, rather than just building on bitcoin.
I lost money by hodling altcoins. I might make money by having deals with them, I don't know. But when I do, I'll be sure to convert any gains back to BTC. Hopefully I get a handful of projects going forward and they'll do well enough.
I read about that ICO that converted whatever they got into stablecoins, so at least maintained and even improved on their initial funds while paying everyone that needed to be paid (devs, marketing, etc.) That's a good example to follow. Sort of like insurance.
Probably a better example to just stick with bitcoin related matters.
Likely plenty of money to be made through bitcoin especially if someone has a 3.5 years or longer holding time (may need to increase to 5 years, because history does not always sufficiently predict the future).
