Well seems like criteria of number 2 is suitable for me, i personally buy bitcoin as much as i can, collect and hold them for long term investment purpose, cause i truly believe that bitcoin's price would be sky rocket in many years later that's why i am not worried whether the price down or up even though just a little. Trading bitcoin at this point would not make you rich except if you have a lot of money or bitcoins for doing so. So far long term investment is a good option for me, i have lost the chance when the price was 200 dollars i didn't buy much bitcoins at that time, now i would not lose that chance again.
It is a good lecture ,when you had the chance to grab some coins when it was two hudred dollars you never made a move and now you are planning to collect as much as you can,it is a good process if you are having a big enough bank balance and even i would buy a million worth of coins if i had the bank balance. 
with the limited bank i do worry about the price a lot and i do always get the timings right when it comes to bitcoin and i am happy with it.
