You don't want to directly mention BGB huh? But you already mentioned it there, lol. Anyways, crypto is still crazy even up to now and in fact, it's craze have increased due to adoption and then there are lots of additions right now but unfortunately NFT's didn't catch its speed and it got left behind. Didn't new NFT's where that long. Phew, time flies so fast eh? You still can make money on your own.
You don't need groups but to answer your question if how did I get involved in crypto, I only come across it in some techno forum and then my friend also talk about it to me, so that's the time I did more research. Eventually I discover the forum through Google and that is how things got more serious.
