If I was in you, I would just hold. BTC price has a very high probability of increasing substantially in the following months and years, so I think it's a bit pointless to spend them. Just buy and hold as much as you can afford.
I do agree so. However, using bitcoin is the most effective way to make the prices keep going up. We must use Bitcoin in order to influence the prices and make it more popular to this planet. As you can see, if no one use Bitcoin, it will be dead. Save the half and try to use another half in various ways. You can buy a lot of things online with bitcoin, you know
