Long term (since 2011), the price has had some large swings but overall maintained a roughly 0.24% per day increase (roughly 2% per week).  Fluctuations now are less than in past years, meaning less dramatic increases - and less dramatic downturns as well.

Graph up to mid-July, 2017:



If, on average, 2% per week increase isn't enough for you, then try the alts, but for now the trend indicates no signs of changing. 

Again, the long term strategy of HODL remains valid.
