bet on sports

I've noticed in a lot of your articles and columns that each betting sequence starts at the table's minimum. In blackjack for instance the first bet is $5, correct? Then what? $5 again or $10? I then understand a natural progression of raising the bet and pulling back a profit. The first bet at a table whether blackjack or outsides on roulette should be more than the table minimum, $10 at $5 tables, $15 at 10's and so on. This way if you do win the first bet then you drop your bet down to the minimum. If you lose the next bet you're still showing a profit. Not bad for winning one and losing one. What are your thoughts?
The betting at Blackjack is based only on the count of the cards. Since the casino usually has an advantage on the first hand, we typically bet the table minimum. There is no betting method that will overcome casino's edge at most games for very long, so I don't support such 'schemes'. If the casino has an edge, you should bet the minimum at all times, because all a progression will do for you is raise the average size of your bet and you'll lose more quickly. Unfortunately, there's no way to get a permanent advantage over any casino game other than Blackjack, some slot machines (with a 'banking' feature) and some video poker games. But, hey.... three games that can be beaten aren't so bad.
