Yes because the price sky rockets from time to time.
I`m holding my bitcoins for 6 months and the price increased from 600$ to 730$.
I can`t say it sky rockets,but it`s a good increase.
Yes,it`s a good way,but you have to buy and sell at the right time.
How about trading bitcoin against altcoin while waiting for the price of bitcoin to skyrocket?
You said that you are holding your bitcoin for 6 months and you have a growth of 130/600 or 21%.
What if you invested your coins in some ICO, let us say PSB.
Let us say you have bought 1 BTC and you invested that in PSB during their ICO.
PSB ICO price is around 323 satoshi per coin, so that gives you 309597 PSB.
Now that PSB price is around 1800 Sat, and you decided to convert it back to Bitcoin and you will get 5.57 BTC
and then you decided to convert it back to dollar at $730. You will get $4066 and that is 677% growth.
I am just showing some statistics here if you invest your bitcoin to some profitable ventures to increase its value exponentially. The value shown is not calculated at PSB PEak which is 9960 satoshi coz if we calculate it that way, you will get more than 30 BTC and that is convertible to $22510 a 3700% increase of your fund.
Of course you need to do your research and take the risk at the same time.
And yes I'm suggesting to invest your BTC while t waiting for price increase.
