Expectations will always be there for Bitcoin especially for long term. Many are hoping that Bitcoin can finally reverse its current trend and go back to the bull market, many are expecting this to happen early next year. Other altcoins will surely follow and that is Bitcoin leads the whole market. BTC should really be the best option for long term, but its advisable to diversify so its good as well to have some altcoins.
Even if this s true we still nee to be careful, when it comes to the markets our timing is really important, while investing in bitcoin is a good idea some traders may then think that it is a good idea to invest in altcoins as well, but this is not correct, there are many altcoins which have yet to disappear during this bear market, so it is important to stay away from them and only invest in them if the bull run is already underway.
I feel like timing is not as important when you get as it is when you get out. You could buy bitcoin at any point, it could be at 17k, it could be at 67k, sure it would be sad if you bought at the top, and you would be upset about it, but you could buy more and more and recover that, there is a solution to it and that's the good part about it.
However, if you bought even at bottom, even if at 16k, and sold now at 17k and then the price went to 100k, that would be sad and there is no recovery for that, you would have to buy along the way again for higher than what you sold, and sell again later when it's even higher, not the ideal situation to be in at all.
