According to Market the lowest value of Lowki at the moment is 40K whereas Guru is 10,000K (10M).
Contrary to what one thinks, at this point of time. 250 Lowki is the equivalent of 1 Guru Cr. 10,000K/40K = 250 Copies.
However I do not have Guru Cr, again merely here to help as the offer is interesting.
