Bitcoin Forum

It is been a while since people started to invest their savings, assets and so on in BTC and other cryptos. As we all know for economy growth money need to be transferred from one place to another, more and more trades need to happen all over the world, etc. However I was thinking of the following now most of the people bought, but keep their money as an long term investment, keeping this in mind what will happen with the world economy and how it will be affected if Crypto world becomes bigger and bigger? Are new market rules going to be implemented? What we can expect if suddenly even more people start to buy or otherwise a lot of people start to sell? Apologies for sounding unclear, but I just can't imagine such big money flow.
