The combination of at least miners selling Bitcoin, an optimistic long-term technical structure, increasing HODL and growing interest from large investors and institutions, increases the chances of a new rally in 2021.
I suppose this pressure acted in weeding out the amateur miners and only those with enough resources and who were proficient enough remained. This turn out of events is not completely unexpected as even if the pressure is felt by others the gaps will be sealed, especially when taking into account the grand scheme of things. The halving only restrained resources, made it more difficult for miners but the rewards are just as measurable, and I feel that the industry is one in which adversity won't win.
