In my opinion gambling is for some lazy lucky guys who don't want to use his senses to be able to earn or grow his bitcoin. He only depends on his luck and click his way out to earn more. I would say gambling is not recommended to those who suck when it comes to lucky chance. I am agains it to use as a medium to grow your BTC because of the huge possibility of you losing all your investment in gambling.
It is true that a serious minded person will always seeks for a tangible means for earning a eaving instead of gambling their hard earned money and waiting to get uck from others that might loose their own stake in the gamble.
A better way of earning is actually when your provide goods or services in exchange for money, in this regard, both the buyer and sellers would be happy at the end of the transaction.
No doubt, gambling is not a source of income where you invest and get profit all time, It is totally risky, I think gambling one of the most risky way, where you invest your money, and no guarantee is here, Even you have a lot of experience of gambling.
More than other earning ways are here to grow the bitcoins, only need knowledge and hard working, If we adopt both things than no one can say that i can't grow my bitcoins.
