I do agree that 100k by the end of this year is quite possible, not sure about 150 but that could happen too, depends on how we go on. I understand that life could be a bit troubled and not all we want could happen at any given moment, but we should probably consider this as possible.
I feel like the most important thing right now is to keep holding because if we believe that it will be 100k then we should be expecting it to grow, so there is no reason why we shouldn't really see something that big. I get that it is going to be difficult, but it wouldn't be impossible neither, it could happen. So holding, and even maybe accumulating some more, no matter if it is high now, could be a great idea to wait out until it reaches that 100k.
Reaching to 100k$ is not impossible but for it we have to increase our patience because it is not going to happen in few months. Its up to us that how long we are waiting but sometimes people loss lots of opportunities due to dreaming for more.
100k$ achievement will only become easy if people don't sell their bitcoin during or after halving because once selling initiates then it will take longer and longer time to recover back to the maximum gain. If one beleive that his target will be achieved then waiting more is not a bad idea but I think that a person should stand firm with his target instead of changing his decision when market face decrease.
