In my opinion, there is no guarantee that after the Bitcoin halving, the price will always go up, it's been 2 halvings, the price of Bitcoin has always increased and reached new ATH...
Of course, there can be no guarantees in cryptocurrency. It is possible that the increase in the price of bitcoin will occur later, but there should be no doubt that the price will rise, since the increase in the number of coins on the market will slow down. If by that time the demand for BTC also increases, then this will further contribute to the price increase.
Bitcoin has to be bullish if you want altcoins to be bullish too,
we'll see right now that the price of bitcoin has been bullish so in my opinion altcoins are still safe if you want to buy them safely.
there are still many altcoins that are still in the bottom if you are afraid to buy it of course it will be a regret,
Bitcoin is already at $ 30k and will continue to be bullish.
