The cycle will come when the government throws some regulations at it. We can expect some of that next year. Besides that its going to a whole pack of EVERYONE trying to get a piece of Bitcoin's a$$.
Also, there is a risk of the economy crashing and that will have an impact on Bitcoin (negative or positive unknown).
The halvings and other known issues will not cause a cycle since the market is far more mature now and will already price that in in a stable manner.
Economy is not likely to crash. Stock market might crash because its very over valued, but with vaccine getting out next year, sane leadership in America starting Jan 20, and the gradual renormalizing of life, people will be heading back to work and the economy will start to improve slowly.
And government regulations aren't going to do anything to the market cycle. The halvings have always caused the cycle, though now we might be in for a mega cycle in the years to come rather than the standard 4 year cycle which would be coming to a close in a year.
