The problem is such look like a safe bet when in fact not... I have seen people lose on a 1.005 odd bet which looked like a sure bet but turned out to be a high risk bet that will lead to losing and the unfortunate thing about such wagers is that a player needs to put in alot of money to have a small profit but in the end its all burst! Btw I think bookies actually make more money on such bets because of our greed, it's a hard lesson learnt and can never be too sure of an outcome.
sometimes odd bets are misleading and gamblers are sometimes too greedy after seeing odd bets that seem to promise victory even though they are like a trap. I had experienced something like this at that time, but luckily I gambled just for fun without using big bets.
for gamblers who have lost a lot of money because they have bet a large amount on odd bets, hopefully that will be the best lesson not to be greedy in gambling
