Bitcoin has always been in the bull-run, except maybe when there is a fud, like the china news and Elon Musk tweet affecting the market negatively.
FUD was always there since the start that could affect the Bitcoin price but IMO on this year, there's no bear market that has happened. It considers market correction and not totally a bear market, so meaning to say, we're currently still on the bull market and the price keep climbing up since the mass adoption was in the process.
Potentially the bull season will continue because people will always have a technology adoption, which means blockchain and Bitcoin could be possible always be used. Another factor is international acceptance, more and more countries now open their gates towards cryptocurrencies could be possible a massive adoption. Once we're on the top, the media spotlight will be the next, and Bitcoin and other crypto will not stop spreading out.
IMO, Bitcoin will always have ATH but definitely, there's no infinite growth, it's always expected to have a correction.
