Bitcoin will easily surpass $100k. They are estimating Bitcoin to climb as high as $500k before settling around $250k.
"They?"

Not that I would dismiss the $500K target. It's very possible, but also completely unpredictable. The next cycle could top out at $200K, $500K, $1M..... all are within the realm of possibility.
The dump as it happened in 2017 cannot happen because PayPal and Square alone are buying up all the Bitcoin being mined out.
Are you sure you're not overestimating the importance of mining supply? After 3 halvings, miners are not the primary source of supply anymore.
Square's ~4K BTC investment aside, Paypal/Square are scooping up so many BTC because their customers are buying. Same with GBTC. That's bull market behavior. Hypothetically after the next bubble pops and the tide turns, that trend will reverse.
