Am I missing something

[sodapop89]

Hi Everyone,
I'm still very new to crypto trading and learning and I feel like I'm missing something. Any help would be much appreciated. Thanks
 
1- So lets say I go to Coinbase and buy 500 dollars of bitcoin at 13,309.75 which is in Canadian dollars 0.04 bitcoin. Then I transfer this to gdax  where I sit and wait for the price to go above 13,309.75 and then sell. I don't see how I could lose money. My bitcoin is just sitting there. I understand that bitcoin fluctuates but somehow I always see it going back up. I hear a lot of people say you can lose tons of money very fast. If someone can explain if im correct or am I missing something.

2- How much bitcoin should I start of with approx:

I'm not sure I understand the question. At this point Bitcoin behaves like a volatile commodity. And in any market, especially a volatile commodities market, you can lose money. If you bought Bitcoin when it was $16,000 you would have, as of today, lost money.
