Just start mine cryply on raspberry pi.
Its about 4 crp per day. If you have idling any pi board just start mine crp on it.
There is a miner
https://github.com/cryptozeny/cpuminer-mc-yespowerBefore compile it you need to change file yespower.c
Find string
static const yespower_params_t yespower_BITZENY = {YESPOWER_0_5, 2048, 8, "Client Key", 10};/ ZNY
And replace it with
static const yespower_params_t yespower_BITZENY = {YESPOWER_1_0, 2048, 32, NULL, 0};/ ZNY
