To answer the question, one must find out WHY people like to gamble....
1. Gambling can be addictive & cause harm to most, whom dream of getting rich fast. Thus when they lose, they presumed that further gambles will not only gain back what they lost, but will get more. Some lost even family fortunes with such assumptions, & eventually their lives when they could not face up to REALITIES of their situation....
2. Our govt under our visionary & wise Founding Fathers had banned gambling for decades as they realized such hard truths & tried to prevent our forefathers from harm. Unfortunately, many still took to underground illegal gambling halls & worse - were cheated by UNREGULATED gambling operators using various tricks & become far rich & powerful than honest tycoons & working men. The HOUSE will ALWAYS win, based upon proven mathematical science of probabilities....
Thus, casinos were finally legalized, & REGULATED to ensure the common man will have an even chance, if they so desire the addictive thrill & excitement from gambles, along with funded advisory campaigns to all, to SPEND ONLY WHAT THEY CAN AFFORD TO LOSE, & not one's life savings or savings meant for retirement, BTO flats, that necessary overseas trip to recharge, etc, etc.....
3. Similarly, ETF - exchange traded Funds such as Bitcoin, Ether, Dodge coins, etc - are BACKED BY NOTHING unlike US Treasury Bills which is backed by REAL resources, Rule of Law & Might.
With such ETF tokens, you buy at your own risk. If it rises in value, good for you. But if the value drops, you will only end up with a token that no one wants & for sure you cant eat it to feed your empty stomach.
Worse if you exchanged REAL MONEY such as life savings in readily accepted promissory notes backed by central banks - currencies, Treasury bills, etc , funds for other necessary expenditures, etc, for such tokens.
4. Thus, as the appetite for gambling & speculative funds along with get rich quick notions, it is only natural that govts whom will need funds for social expenditure such as healthcare, education, infrastructure, etc, they will change minds to allow such activities & gain from it, as the HOUSE will always win.
All it needs is just a few tokens, a few millions to PUMP up the token's value, & fools will rush in......
When it is time to pull the plug, which is decided by the creators of such tokens whom will need to fund other enterprises - fools would have lost everything.
Thus, my appeal to all is to gamble only upon WHAT YOU CAN AFFORD TO LOSE, & not your critical life savings or even life...please.....
Life is no bed of roses, but should one be smart & hardworking, success WILL come thru such means & not by any other. Some will claim luck but such is not everyday or for life.
