So basically you do the same thing but narrow it down further to $50-100 above your buy in price?
Sort of. You are taking a longer veiw on the market than I am comfortable making. I typically play the market shorter term, so the way I approach it will vary highly depending on what the market is doing at that moment, and how confidant I am that BTC will hit my target prices.
For example, Yesterday I made several trades, and most of the sales were within 30 dollars or so of my buy price. I kept it tight because I wasnt overly confident that the price would stay within any given trading range and wanted to be in and out of trades as quickly as possible. I also wasnt sure how low the price would end up, so I chose to stay in USD as much as possible (allowing me to preserve realized gains and allowing me to pick up more BTC at the points I bought in).
However, today I stayed out of the market completely as I never felt comfortable in which way the market would go. Instead of trading when I was unsure, I put in a low buy order at a price I could live with if it got triggered (in the 400s) but overall stayed in USD. If the price starts to take off before I can get in, thats fine as well...I'm very OK with missing potential profit if it means protecting the profit I have already made. For now, I'll wait until my low buy order get triggered (which I think is unlikely), or I find an entry point into the market that I am comfortable with.
Do you always sell at the end of the day?
I like to have my trades resolved by the end of the day, but whether those settled trades are denominated in USD or BTC depends on the market. During a down market I like to be in USD (to preserve profit), and in an up market I like to be in BTC...that said, when I am in BTC, I generally have price alerts set on my phone so I can take action and bail out into USD if I need to.
We know long-term it is up anyway.
I'll be one of the few people on this forum that will be honest with you about this point....the price wont necessarily go up in the long term. The fact is this whole thing could come crashing down tomorrow. Maybe we will go steadily up, or maybe we will continue the bubble and bust cycle with the price fluctuating up and down wildly, perhaps the price stabilizes and we trade sideways forever, or maybe a flaw is discovered in the system (or maybe people lose interest or whatever) and the price crashes down to singles (or lower) and never reaches old heights. The fact is, we dont know what the future holds for bitcoin, and there is certainly no guarantee on future price.
Please dont listen to the hype from the echo chamber. Go into trading with open eyes and realistic expectations, or you may get burned.
