He spoke of Bitcoin's market cap, just to make that clear. But in another interview which can viewed on youtube also, he said that Bitcoin will be worth $100k each!! He didn't mentioned any time frame he expects that to happen by the way, but he beilieves these numbers are possible. Max is covering Bitcoin since many many years now. He has been one of the first guys out there from the media landscape doing so and has known figures of the industry as guests on a regularly basis.
The prediction about bitcoin market cap reaching 1 trillion is the lower prediction since bitcoin will have to grow 15 times, while the prediction about the price of bitcoin reaching 100k will need bitcoin to grow about 25 times in market cap, both of them are very high but the easier one to reach is the prediction of 1 trillion dollars in market cap.
Look at all the other markets, Forex, derivates, bonds, stock, commercial real estate, art etc.!!! Compared to that Bitcoin and the crypto landscape still is very very tiny, mostly a joke and not worth any mentioning!
Try to get the bigger picture! With cryptos we have completely new trading and asset classes. Very cheap in commission, can be traded super quick and 24/7!!
This market will have a huge and bright future! And once some bigger money from the other markets start to come over, $1trillion marketcap for BTC and $100k per coin isn't that far fetched! Give us another 10-12 years and you will be amazed how far we will have come. Future traders, investors and speculators or even just normal people outside will have to work much harder to achieve just 1 BTC as a goal, a BTC we are taking for granted and sometimes as not that much of thing right now. Therefore accumulate as much as you can I say! Each bit counts!!!
