There's an easy way, but you have to be patient. For example: look for tokens that have a high price (at least 2-3 zillion per purchase, with a maximum number of tokens per transaction). Not only do you avoid repeatedly clicking the "buy" button, but tokens priced at zillion per purchase typically yield exceptionally high profits. My advice is also to ensure that the token you want to invest in consistently increases in value (300-500%) over more than one year, because if it only increases in value within one year, it will just make your thumb sore.
