Switching programs always chase the hot coin  and are always  behind the wave.

You should not use them.

You should pick coin A ------ stable money maker  mine it six days in a row and sell it.

You should pick coin B  ------ A shot in the dark mine it 1 day and hold it or list it at a stupid high price on an exchange.
  Say  it is worth 1 dollar when you mine it.  list it for sale at 10
  Every 7th day mine it and list it for sale at 10x the price you mined it.  This is your I made a fucking score coin.  


Coin A is your it pays the bills coin.


Say  you do xmr  with that card  to pay the bills 6 days a week  and do zcl 1 day a week listing it at the high price. If zcl takes off you score.

and xmr/monero is paying the bills for the six days a week
