BTC is a revolution, thats why its caught so many off guard with its growth. ITs something new, to consider prospects long term I dont think the price is really giving more then short term sentiment.
Prices on exchanges dont really determine direction, they are playing games trying to buy and sell into a profit and they have no genuine need otherwise. Thats not a product to play a trade, its arbitrage but real selling by miners and then buyers who need BTC to transmit value. Its always the customers that determine real demand and also the pricing that occurs over months to years.
Your question seemed to me to be about the long termers view, people who saw this kind of dip before. I would just say read the news on events, development of the protocol and perhaps also rivals. Fees are highly relevant to usage growth, also I think mining efficiency is relevant to supply dynamics though BTC in theory always regulates constant supply rate.
I also read about dollar and US treasury debt, the prospect for that determines the weight of the other side to the scales and so part of BTC price. Thats I guess another subject but highly relevant as crypto is used globally like dollar
