It'll definitely get much easier to buy bitcoin over time. That's inevitable as Bitcoin continues to grow, more people adopt it, more companies want to make money by offering it, and it becomes more engrained in society. It's already very easy to buy now in free nations - like in the US you can easily go to a number of exchanges to buy, buy on Robinhood, cash app, PayPal, and more. Institutional investors have several options now as well.
Where it should get wayyy easier in the years to come is for the traditional stock market investor to buy through the same service they currently buy their stocks through (their brokerage account or whatever) and to buy Bitcoin anonymously. Buying Bitcoin anonymously now is relegated to a few sites where you end up paying a pretty markup on the price. In the future, as more people use Bitcoin, and as government try to react to Bitcoin's growth more by surveilling it to a greater degree, I'd like to see a lot better options for getting Bitcoin anonymously away from CEXs so that your every transaction is attempted to be tracked by crypto tracking companies and the govt.
What about the KYC's? They are being rampant now. Started from the exchanges and now they are dominating the gambling scene. I am afraid this trend can continue in the latter stages. We all know that many of us are also allergic with these KYC.
This makes them experience a difficulty on looking for an exchange which doesn't require a KYC but at the same time safe and is great to use just like the ones that we know on the past before they became more stricter. Yes, you can now buy btc in PayPal but the problem with PayPal is that you can not send your coins or receive a btc from someone else but this may not be the case for others.
