If BTC will see adoption like XRP or BCH then there will be a chance for another bull run.
Lately, I don't see the adoption of BTC growing only something opposite merchants stop accepting it. High fees (50$) for a single transaction when BTC was at ATH shows that this is not possible for Bitcoin to be a widespread payment solution because of the scaling issue. Ongoing for years debate on the scaling issue brings nothing besides new coin BCH which is now one of the biggest BTC concurrent on the market. I still don't believe that we need an LN on top of BTC and even if then we should let the blocksize grow until LN will be fully implemented/usable.
If Bitcoin resolves all burning problems then and only then will be a chance for another epic bull run. If not we will slowly see like Ripple, Ethereum and Bitcoin Cash are taking BTC place on the top of the coinmarketcap list.
