anyone actually running the numbers to check these claims?
Actually since I mine and do not buy and hodl the people that compare the two are always wrong.
They are not comparable other that they involve crypto coins.
Best example is this
put $1,000,000 usd in the bank and collect interest = buy and hold.
put $1,000,000 usd into a fleet of limos and open a wedding + party service.
they both involve 1,000,000 usd that is all they have in common.
Same as buying $1,000,000 in btc and holding It.
or buying a $1,000,000 mining farm.
they both involve 1,000,000 usd to start up that is all they have in common.
Now you could compare
putting 1,000,000 usd in the bank and collecting interest on it
to buying 1,000,000 usd worth of btc and getting interest on it from an exchange
