=0.01btc a day for 14days=0.14btc
difficulty adjustment 5%=5% less per fortnight
...
total after 36month 2.73029601
so they want you to pay them 3.448btc now ($200k at~$57k/btc)
to receive 2.73btc in 3 years
anyone see the problem 3.448 in...2.73out
but 5% adjustment per period is questionable going forward.
In fact, there were similar calculations pooh-pooing buying of miners (s17, t17) before and immediately after the last halving.
They paid off spectacularly, even in btc.
Plus, it is aimed at those with euro, not btc. Mining smoothes out the return ( you are not buying a lump sum of btc at the current price).
They just have a price a bit too high, we both agree on this. About 20% less would have been prudent.
in the last 6 months. there have been a few difficutly adjustments exceeding 10%. so 5% was quite fair.
i also have looked into some asic studies of this month.
such as slush pool 'active workers' have a 25% using s19 and 75% using s9..so there is still alot of hardware upgrading to do yet
oh and the pitch is not about euros
Dr.Back"If you hold Bitcoin or your business relies on it, you have an incentive to directly participate in mining"
seems he is preaching to those that already have coin.. not euros
but if you only hold euros.
and you done some maths and worked out you can get 2.73btc but only if you hand in a lump sum now. and wait 3 years..
or
buy up 3.448 now. .. no delay. no risk of loss no risk of company liquidating no risk of 'we been hacked'
which would you choose
$200k now...3.448btc now no delay
$200k now... 2.73btc later. maybe with many if's
