When the tulip bubble popped it went to $0 pretty quick. Experts had been warning this crypto stuff was all hype / BS. I don't see $0 but I see $1000 or so in a few more months. Start investing again when that happens.
This could be true on some specific coins. They are scams and some are only in for hypes but for the coins that represents the crypto market, no they are serious and have a real objective on why there are here.
Those so called experts that says negative stuffs like this are not really an expert because they didn't do a research but there are true experts that encourage everyone to keep on buying during this dip. They are the ones that knows the technology behind cryptos. Cryptocurrencies are not only about the price anyway but their main purpose is about being used as a currency. Bitcoin that 22k right now, is still the bitcoin that we know when its value is at 30k.
