I think those who do not have the patience to savings, those will never be able to savings, no matter what method they use.
But for those who have the mentality of saving, I think this method will be really fruitful. Moreover, another way of saving can be done through Bitcoin, where by setting a transaction time of Bitcoin, it will not be transferred to any other wallet until the set transaction time is over. I think it will work for those who are very impatient.
