People have to think about what makes a coin go up. It goes up when money is pouring in. When people are buying and buying and buying. We saw it during the bull run in 2017. That was huge. Yet it went "only" to about 20K$. To go to 1 million, you'd need billionaires investing massively in BTC. Since they're already billionaires, why would they risk it ?
Well, I'll say just two things here.
One, there actually are plenty of billionaires investing in crypto. Not necessarily in the currency itself, but there are huge sums of capital going into projects related to the crypto market. Because savvy investors realize that blockchain technology has tremendous potential, and bitcoin growth has gone hand-in-hand with that growth. There is no reason at present to believe that it will not continue to be the case for several years to come.
And with each bullish cycle, we see millions of new accounts created across exchanges. The current infrastructure is struggling majorly to keep up, hence why there is still so much investment flooding into this market. So factor this in with the block reward being reduced to 6.25 next year, and there is a recipe for tremendous growth. For anyone who understands this market, I think you'd be crazy NOT to believe that we're headed for $1 million a coin and more.
