As MCO is a crypto coin, you will be subjected to price swing in MCO price. So ask yourself if you are able to withstand a drop of 50% or even 80% of the MCO price when you stake for half a year? Saying so, do have a look at the tier of 50MCO, given that MCO has been declined from its all the highs for quite some time, the down side is still unclear and that is the scary of crypto. Yet, because it is just 50MCO, you wont have too much to lose. In return, you can have 2% cashback for all your purchases and even free spotify which is quite worth the risk. However do take note that even though the cashback is immediate, the cashback is in MCO form, so you still need to sell the MCO back to SGD and there is a min of MCO before you can sell. Also, you can also involve in crypto earn where you can gain 6 to 12% of crypto interest if you have other crypto coin that is sitting around and doing nothing. Also, the conversion rate is quite good, so you can just credit in SGD and you can spend it on msia and any foreign country without the need to go to a money exchanger. The SGD deducted was comparable to good rate offered by money exchangers.
