I think it's time to start investing in the $BIO coin. Assuming I have $100, I will buy $20 now, when its price is 0.3. When it reaches 0.25, I will invest an additional $30. When it reaches 0.2, I will invest an additional $30. In the end, if it reaches 0.15, I will invest the remaining $20. Then I will wait until I make a profit at a price of $2.5.
