You still have the belief that Bitcoin will grow, your chances of success are very high, It is impossible to know what will happen to how much Bitcoin price increases but one thing is going to increase. You bought it little by little to increase the volume of Bitcoin I really admire.
Well it is a fact that Bitcoin will still grow in the future, we may not have a good experience in the year 2018 and 2019 but still doesn't mean that the journey for Bitcoin is still great! We just expected too much from it so we didn't notice the profit it gave to us if we bought from January 2019 and sell it last month at price of more or less $7.3k.
