Your claim is especially true in crypto-space. A month in stock market is like a day in crypto. Tides will change in a matter of years. I do believe that there is a near 100% possibility of another financial crisis before the End of Trump presidency (poor guy. most of it isn't even his fault).
An even like this will drive many into cryptos. The prices will go up like gold. The increased Tx volume will be very bad for BTC. The forks will be negatively affected by carrying Bitcoin brand and alt-coins will rise.All of this will happen over the course of few months. There will be people who'd still treat BTC as a store of value. But dominance will fall. I mean BTC doesn't sponsor anything. You can't build a business on top of it (like NEM, ETH, FCT,SYS,LBRY, etc)
Above all the reasons for block size limit makes me torn between conspiracy accusations and cringe/apathy towards the small blocks advocates. They make ZERO business sense. One more reason to love Dash. 400MB and beyond.
