Is he right from what you think?
Either he is new to gambling or he does not understand gambling and is addicted to gambling, moreover, an experienced gambler cannot present such a thing. Gambling and investment are never the same thing, you can understand this yourself because investment is keeping your wealth with you or buying bitcoins and if you keep it with you for a long time, it will give you benefits. Once you lose, you will not get the second chance to get your money back.
There is no possibility of getting your money back, how can the meaning of investment and MA gambling be the same, if you gamble to earn money, then you will definitely lose money and that person will lose all his wealth at the last moment.
No matter how people are trying to package it gambling and investments are never and can never be the same, like you have said you are to buy Bitcoin, or stock, even gold, even if the price just drop a little bit you are still in control of your assets, if possible you could even wait till 10 years from now till then and it can recover and you your benefits, and that what we call a second chance….
While as for gambling once you lose the sake it gone, it s just simple and easy way to lose money, you lose and there is no asset remaining, the money turns zero and you never get a second chance, which the only to recover if you are lucky it to start all over again and it a strategy to lose wealth…
Like the best way to Investment risk is managed with time and knowledge, and as for gambling risk is designed so house always wins over time and there is nothing that can be managed about it..
