...What do you think about this? Will the participation of financial institutions have a positive or negative impact on the crypto market in long term?
Positive when we're talking about crypto going mainstream and increase mass adoption.
Negative when we're talking about privacy since regulators will tighten up anti-money laundering policies on all exchanges and custodial services.
I don't know anyone other than a newbie who would expect price to go up forever. FUD, corrections or pullbacks are part of the crypto ecosystem.
