Honestly I dont think anyone can have 100% confidence all the time in trading, There are just too many variables and the market is unpredictable But I do think with experience and a sound strategy you can create enough confidence to adhere to your plan Fear never goes away fully but learning to control it is what makes the difference
As for Bitcoin, I have full confidence that there will be a new ATH this season.
But for altcoins, hmm, not all altcoins are able to do it. It is even possible that some top altcoins are not able to realize the hope to be able to pass the previous ATH.
However, hope is indeed one of the factors that convinces us to still keep holding our assets. But on the other hand, we also have to watch the development of the era, so that we at least will not feel regret if we are late in taking action on our assets
