When I first registered here, the exchange rate was around $10 per coin. I never purchased any BTC or alts. I got them through bounty campaigns and give-aways (back then it was quite easy to earn them). I sold a part of my coins when the prices went up in 2017. So as you can see, I waited for almost 5 years to profit out of my coins.
You are lucky to enter the cryptocurrency world in such at their young age. I discovered cryptocurrency from at least 3 years ago and the price is a little bit expensive base on my salary per month so i just save at least 10% of my income per month and put it into cryptocurrency and just like yours, i sold them at 2018 when the price is high even though it starts declining.
