i think it is, because in the year 2011 you can buy a Bitcoin for only 4$ and if you buy 100 Bitcoin before and you still have it now , then you are a millionaire , and if you buy bitcoin now it's late, because the price of BTC now is expensive
I think that if you value it's true value, BTC is still cheap. If you look to it's financial value, it still cheap.
Picture it this way.
If mcap of Crypto would reach 50% of Golds' and btc would still keep 30% of the Crypto mcap. How much would BTC pe worth at that point?
