If we have less new investors, so the prices tend to fluctuate less? How much dependent of new investors the prices are ?
Look it doesn't work like that. You don't know who is a new investor and who the old investor. For all you can know, one person may be circling his money along through his addresses. Prices are determined by markets. The basic law of demand and supply. Economics? Ever heard of it before?
To many people came on crypto ecosystem and we truly don't know on which of them are new ones. But lets just assume that some of them are big whales that can bring up good fortune on bitcoins aswell with cryptocoins. But lets hope those new comers can withstand the flaws of crypto markets so that they can make the demand more bigger.
