It is very clear and looks easy. But do you take into account the panic when the price is 0.9?How about buying 300 and saving it until at least next year. You do not have to worry about anything other than losing 300, or get 30000.
Well I recommend you the basic strategy and effective strategy here in crypto world, if crypto coins price falls down, wait it to the minimum price and invest it hold it and wait until it rise if it rise sell it then you'll earn profit. Buy, Hold and Sell.
