Short term price doesn't mean crap if you're bullish on the long term. It will only be "difficult to buy" if all you care about is short term profit in USD.
Tell you what, if bitcoin reaches it's full potential, $25,000 is NOTHING. Don't underestimate the 21 million hard cap.
Bitcoin is getting closer to its full potential with small steps every year and yet we've seen a drop from $20k to approximately $3k from 2017 to 2020. The price will be whatever people would be up to pay, and getting closer to its potential does not equal another unimaginable price push. The USD in circulation is around $2 trillion. The chances of Bitcoin becoming a trillion dollar market cap are not very small but are smaller than we probably think. If we look closer at the situation though, while BTC is getting closer to its full potential it's also staying away from it at the same time. Laws, regulation and everything else pushes away Bitcoin from its real purpose. The true transition from third-parties to peer-to-peer economy will never happen. Imagine it as a big wall sitting right in front of it.
