Yes its true that Dogecoin was NEVER mined with CPUs. There was a short period when Scrypt was introduced (Litecoin algo) and it was CPU only at first. However GPUs quickly came into the game shortly after. Then the ASICs came and bye bye GPU mining.
There is actually a rumor, no idea if its true. Read it somewhere on the Litecoin reddit. But apparently they say that some LTC developers had a secret GPU miner software while only releasing a CPU version. So many suspect that some LTC devs mined Litecoin at a huge advantage. This is pure speculation and no idea if its true, way before my time in crypto. Maybe some old timer can confirm or deny these allegations.
forum member kano has said that the ltc developer put out scrypt for cpu only but that he had the ability to mine it with gpus.
If I recall correctly kano gave a link and when I read it is looks to be true.
Ltc-Doge may have not had the best start in life but they are well backed with asics.
they are very secure.
Ltc makes 2x the blocks that btc makes in a day
doge makes 10x the blocks that btc makes in a day
ltc is basically an improved version of btc it is anti inflationary same as btc.
doge is not as inflationary as the dollar is it has a controlled shrinking inflation.
by this 100000 coins in ten minutes or 600000 coins in an hour.
but over time the percent of inflation that represents shrinks.
ie at time of 1 hour in the beginning 100000 coins
1 hour = 100000
2 hour = 200000. that is huge inflation 100%
10 hour = 1,000,000
11 hour = 1,100,000 that is smaller 10%
100 hour = 10,000,000
101 hour = 10,100,000 that is smaller 1%
1000 hour.= 1,000,000,000
1001 hour = 1,000,100,000 that is smaller .1% hourly rate.
10000 hour = 10,000,000,000
10001 hour = 10,000,100,000 this is smaller a 0.01% hourly rate
that is about the first year.
there are over 120,000,000,000 doge
so 100000 doge is now 100,000/120,000,000,000 the hourly rate is now very small
