What do you think can be the biggest threat for Bitcoin in current situation? In my opinion it can be only some sudden governments shift in regulations and laws to ban Bitcoin (which I don't really think may happen), otherwise there are basically no obstacles or threats.
I always held the same view - if global players decided to fight Bitcoin, it would be in a very bad spot. All exchanges would close, so the price would crash hard, and liquidity would be reduced to a fraction of pre-ban levels. Same with adoption - Bitcoin would be pushed exclusively to darknet markets. Very few people would want to deal with currency/asset that can land them in jail. So, the fact that Bitcoin's network can't be destroyed does not mean that governments can't harm Bitcoin.
