Congrats. But I still think that in the long-term, buying at - for example - 16000 USD is not really a bad thing. You just need not to worry about your investment and try not to unnecessary speculate on BTC price. As many people say... invest only money you can afford to lose. I know it is hard to resist to those news talking about Bitcoin going to zero, but your emotions are not reasonable and these predictions are definitely not realistic, just as those talking about 50K at the end of 2017. To newcomers, I can only recommend hodling (maybe it is a good idea to sell it back to USD when the market is up, but again... there will be your emotions playing a big role, they will try to force you to stay in the bullish market... but you have to sell your BTC sometimes - if you are not so enthusiastic that you would rather wait for the world around you to accept BTC)
