The scamming will continue for as long as there will be naive newbies who believe that they can invest in "good project", and it seems there's still plenty of such people. Nowadays most people know about the dangers of shitcoins, ICO scams, pump and dump and so on, but somehow they believe that they posses the skills to avoid it. and this is where they are wrong. My advice is just stick to Bitcoin, it can't be manipulated in the long run and it's the least risky coin in this whole market.
Yes, bitcoin is more reliable for investment than any other altcoin. But from the point of view of short investments, altcoin is often more profitable. We know that when the market falls, it is more profitable to hold bitcoin, and when we expect the cryptocurrency market to grow, it is better to invest in altcoins, which have fallen much more than bitcoin and which will have to grow stronger than BTC.
