I'm new and only recently heard Solidcoin even existed. Recently I found one really small exchange still trading it. I never even heard of tenebrix/fairbrix until, now. None of these coins are even on coinmarketcap and there are some really shit coins right at the bottom of it.
If there were only a few alt coins back in Solidcoin's day and quite a few seem to be dead, how many of today's shit coins will go the same way? I bet that in a year's time newcomers will never even know half of the coins on coinmarketcap today even existed.
I never heard of tenebrix/fairbrix until just now either. I think the vast majority of current coins will vanish within a year (or be so meaningless that they might as well vanish). Even good coins will probably vanish shortly thereafter. But the exchanges may keep some coins alive longer than they really should, I expect. Even now, coins that should vanish are still listed on some exchanges.... nobody uses them, they barely get any trades, but they remain.
BCX sort of answered my main question. I was less curious about the million alts/shitcoins and spamminess of the forum, and more so in regard to the general tone of the forum and overall immaturity. I guess in a forum with little to no moderation, and a topic that appeals to human greed, it shouldn't be unexpected really. It just seemed weird to me. I also agree with Igotspots ... I haven't ever seen a forum with so much hate as here before... although hate may be too strong a word. Perhaps lack of morality would be the better term to use.
There are many divisions within the community and most are based on money/perception of gain or loss.
Most euphoric couple of weeks in a long time.
