buy 33 dollars of 3 up & coming coins when they are priced at 1 cent, preferrably less. Even if 2 fail, when the other is priced at 2 dollars you will start making a profit.
the price of the coin might not be the best thing to look at. more relevant is the market cap. e.g. if the total supply of a coin is very limited, the price of one coin might be above 1$ while the market cap is still very low compared to competitors. thus a 1$ coin can have more growth potential than a 1 cent coin.
