I don't like doing my homework and and am not very good with numbers.
Utter nonsense about Dash having bloat, I did these calculations a while back (end of January), others have seen this post before.
Please do check my numbers if you dare.
The stats used are from bitinfocharts:- Darkcoin blockchain size = 0.5715 GigaBytes Days since genesis block=370 days
Average Rate of growth for blockchain per day=1.5 MegaBytes/day quarkcoin block size = 2.4 GigaBytes
days since genesis block = 550 days
average rate of growth for blockchain per day = 4.3 MegaBytes/day
litecoin blockchain size = 3.99 GigaBytes
days since genesis block = 1201 days
average rate of growth for blockchain per day = 3.3 MegaBytes/day
dogecoin blockchain size = 8.49 GigaBytes
days since genesis block = 412 days
average rate of growth for blockchain per day = 20 MegaBytes/day
bitcoin blockchain size = 34.3 GigaBytes
days since genesis block = 2205 days
average rate of growth for blockchain = 15 MegaBytes/day
Monero blockchain size =3.5 gigabytes days since genesis block =303 days
average rate of growth for blockchain =11.6 megabytes/day
