If people stop putting money in Bitcoin, who does not have any use at all apart of been in ur wallet and been and asset for exchange in a market (like bitconnect coin) what will happens???
You already have the answer

The conclusion is, once people stop investing in Bitcoin, your whole investment may plummet down.

Think about it .... just saying.

Edit; Change Bitcoin for many other coins that we have at the moment ... and also think that Bitconnect have a big community around... bigger than many others. Sometimes is the only thing needed for get the stuffs working, people who believe.
