ETH seems more predictable to me. OP, if you still have 50% of your fund to allocate then I advise you should invest in ETH. I expect a sharp downward after the PoS Merge and recorrection after that. Better lay up your orders for the ETH dips.
You are thinking that ETH will be dumped as soon as the merger is over. it's a well-founded prediction but you should keep in mind that the market and ETH are still dependent on the movement of bitcoin. If bitcoin rises in price at that time, it is unlikely that ethereum will be dumped but will follow the trend of bitcoin.
Predicting the direction of bitcoin or any coin is very difficult, there are no guarantees. Your prediction for ETH, I think many people have also thought, and do you think that when everyone is predictable it will still happen?
