First we need BTC to get to a trillion market cap, which I think is definitely doable IF it becomes more easy to buy. Less KYC, more ATMs, but with governments seeing btc as a challenge, that seems unlikely. A lot of media excitement at Bitcoin breaking a 200 billion, 500 billion etc market cap could get it to a trillion.
Could it go on a massive run and spike to 20k this year? Sure, who the heck knows. But to be sustainable it would have to be supported by something, maybe if a country or two adopted it as their national currency.
1. Less KYC? Not gonna happen. Not at all. Authorities tend to go to the totally opposite direction. We expect that opening a single wallet would require the same procedures as opening a bank account. Including signing the declaration that the coins/tokens belong to you and you only, the purpose of opening the wallet etc.
2. Something, like lifting almost global advertising ban by google, yahoo, facebook etc. would be enough. But in general, if we are speaking about the countries, we think Africa has such potential (starting with countries with the extremely high inflation rate, in some already USD and GBP are used literally as parallel currencies). They were the very first to adopt mobile payments, before more developed countries. They simply passed a few stages of infrastructure development (what was an incredible proof of showing human potential).
