To what extent do Exchangers affect Altcoin prices?

Hello, everyone. I'm asking myself how you see the situation.
Many newcomers to Altcoin are looking for the easiest way to make their first steps.

Exchangers like Anycoindirect or LiteBit are probably the first choice to get started without any dissuasive verification. Recently, however, new customers have been blocked and there are minimum sales (e. g. Anycoin at least 100 EUR per purchase).

This is undoubtedly deterring many potential investors and the crypto-scene is denied potential inflows of money, which slows down demand and hence the development of prices. Or do I see it too dramatically?
