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.
Amazing graph and very telling, so bitcoin can give to us in two weeks what banks give in my country for the whole year? And I keep hearing people close to me saying that I should put my money in a bank, it is very likely that if things keep going like this I will be able to retire in less than a decade while my friends and relatives will need to keep working almost all their lives.
