In one year you can make 4BTC its very good I think. 
And how did you make them ? trading ? mining or doing something ?.
My advice for your coin just Hold that coin until the price hit 1k don't gambling your coin.

The chances to earn the same amount next year are less.
Because i think that the price of bitcoin will be increased.
And about the source OP has already mentioned that he earned those from mostly selling stuff or doing services and little bit from signature campaigns and not from mining.
