I think BTC halv should get things started again. Unfortunately , the next halv is in Apr 18, 2024 01:59:44 AM UTC around that time so we are still 1.6 years away.
Any other reasons for BTC to pump would be the cycle between pumps so technically we should have a pump on late 2023 beginning of 2024 and this is what my predictions has always been and still believing that BTC should be under 15k$.
Agreed, halving will surely bring big price movement in the market. To experience the same we need to wait for a long time. Meantime it is good to earn something out of the market volatility with bitcoin as well as majority of the altcoins on the top.
Any other reason that can pump the market is a massive adoption. News similar to a country making it legal tender would make some positive move on the market.
