I am sorry but this is kind of boring. Like you have 0-49 you make a profit and from 51-100 you lose profit.
Therefore you are just blindly betting in this situation. You actually have better odds in high or low (proper high or low) at making a profit. This also has some pretty bad profit margins relative to just going out and buying some shit alt pump and dump coin, risking maybe $3 and potentially jump up something like 500%+ during some pumping.
Ultimately to buy, no. Gambling at pure odds like this are risky and no investor should buy unless they believed that the probability for profit out weights the probability of loss (even if the odds aren't so simple).
