The market has realized most of these coins are worth nothing and the promoters have no intention of developing the ecosystems
You are missing a few salient points regarding the crypto space.
The market hasn't realized anything. Bitcoin is the tail that wags the crypto dog. What bitcoin does, the rest of the alt-coin market follows. The big dip that occurred earlier this year in BTC was the actual event indicating the takeover by the powers that be, who now control the price.
Plus, lumping all developers into one basket shows a lack of vision on your part. Some of our finest people are working non-stop to develop systems to allow the adoption of crypto by the masses. Attempting to undo the damage created by 100+ years of abusive fiat policy by central banks has got to be one of the most noble occupations a person can be involved with today - directly chipping away at the monolithic forces enslaving us with usury.
The crypto markets are mercilessly crushed in the same way the powers that be work to crush our spirit in any matter involving personal and individual freedoms.
Crypto is the biggest threat to entrenched powers since the dawn of written history. Unless something changes, like the masses moving into crypto suddenly, we can all expect to be beaten to a pulp emotionally until further notice.
My advice: obtain as many and as much crypto assets as you can and hold 5 to 10 years. If it works out, you'll be rich. If it doesn't, at least you tried and there's no way to fault yourself for that.
