as we know that in 2017 many ICO were successful (at least reached softcap) and of course the market cap was also very high at the time, so it proves that many people are interested to investing in cryptocurrency, but now where do these investors go? because now the market cap is down and many ICO or IEO are failing (not reaching softcap), are investors no longer interested to investing in cryptocurrency? if yes, where are they investing now? or is there a more profitable investment than investing in cryptocurrency for now?
2017 year HYIP program is very successful, do you know Bitconnect? The investors you are referring to are those, people who don't know about crypto, are invited by bitconnect leaders to join the crypto world, and when bitconnect scams all of them leave crypto
It was a hype time when cryptocurrencies were discussed at every corner. People with no an appropriate experience wanted to make a quick money. And as a result they were scammed and left market. It is quite common situation whent it comes to any overhyped investment theme.
