Did you agree that In order for cryptocurrencies to start growing again, institutional money need to enter the market making the prices soar - That may will cause an increase in volume, making the big players re-enter the market followed by the new wave of adopters.

Yes i did, Because money flow can help crypto to put more daily trade volume in the market. More volume means there will be more demand and interest to buy more and more crypto as much as they can and that will be result in big bullish trend.
I share your point of view, because more volume of trade can be interpreted as a measure of the endorsement and faith in a coin. It goes to show how liquid a coin have probably become and until a coin is liquid enough, it hold little or no attraction for institutional traders because the market could hardly fill their orders. So we can conclude that the entrance of institutional money into cryptocurreny is a welcome development, though there're set backs also.
Entrance of money which we dont even know on what would be the sources either on institutional money or just purely basing on investments of certain investors or traders but well as long theres a big volume no matter which they do came from as long we can able to ride on the waves then it would really be just fine.Continue growing is already happening but it doesnt necessarily to have large volume.
