In short: this idea sounds tempting, but in reality, it's one of the quickest ways to lose cash.
About betting and gambling:
They're mathematically designed to favor the house (house edge).
In the long run, most people lose, even if you snag a win here and there in the short term.
If you jump in without discipline or hoping for the 'big score', it usually ends badly.
About 'purchased fixed scores':
I gotta be straight: in 99% of cases, it's a scam.
People who 'sell fixed scores':
they send different results to multiple clients (some will hit → appear legit)
or they simply take the money and block you
If someone truly had sure bets, they wouldn't have any reason to sell them for a few bucks — they would bet themselves and make serious cash.
real risks:
you're consistently losing funds
you could become addicted (it happens more often than it seems)
you enter the cycle of 'I'll just throw in another bet to recover'
Real talk:
There is no foolproof method to copy bets and make consistent profits. If there were, it would be shut down immediately by the sportsbooks.
If you still want to play:
wager a small amount that you can afford to lose entirely
treat it as entertainment, not as income
avoid 'fixed odds' sold on Telegram or other platforms at all costs
