Whatever the scenario is i think buying btc is recommended especially from dips if you are true supporter of decentralized money, it can also be proven historically that the buyers are in huge profit if you average out the price, only buyers from last peak are in loss they will also be in profit after halving when real bull run will start.
there will be people who can't believe in btc in long term so they buy on peak and sell on dip.
apart from those people we all as btc buyers should be fine as we're heading to future
