I see it as a good news for the price, but not much more.
Things like this can actually be bad for the market and the price because when people withdraw their money from exchanges they are withdrawing/exiting from the market which makes the order books a lot thinner which in turn makes market manipulation easier. Hence more volatility, big crashes or big jumps become easier.
check the numbers
dare i say it... RESEARCH
majority of coin in exchanges are not "on the markets" they are custodian holds or market wall holds at the extreme tops, not meant to by processed today, but just held by exchanges for later.
taking coin out. if it was on the market (near the market price spread) then less coins means less sell pressure, which actually means less pressure to move he coins prices down
simple math(made simple)
if a bunch of buyers average buy amount they deposited was $440 each
and sellers had average 0.02 those orders match at a $22k price
but if coin owners took out 1.3% average meaning they are only offering on average 0.01974 then that sell of 0.01974 for $440 fiat means the price becomes $22,290
yep less coin on an exchange has a positive effect. (if those coins were on the market intended to be spent
(even high school economics of supply/demand knows this)
