well, it's absolute true. You should provide some of your previous betting or at least an history of your past bets.
You have just 3 persons on your telegram channel... and no track history

... maybe post some here so people could following more easily!
I never believe in these ads.. and i explane why
if I'm good at doing a thing or a prediction
why should I tell others?
if I have a method of making money that works, I don't tell others, I keep it to myself!!!
the more people use it, the more you risk crowding!
my two cents
some times it's just the pleasure to share some good tips...and not all bets can be shared
Anyways it can be useful to get some referrals, selling betting stakes, selling "vip bets"....

Always a gambler should share previous bets or it's easy to fool people and this was my request to OP.
If don't have a track record or don't want share... it's just a waste of time and it's very easy loose money.
