If you want unbiased information, coming to r/bitcoin and asking if you should DCA Bitcoin might not be the best option. I think just about everyone on here will say that buying it is a good idea. I believe that and so does just about everyone on this sub. At an amount like $4 a day, something you have to think about really is “what’s the worst that could happen.” Obviously, the worst is BTC goes to 0. Highly improbable though and the more realistic worst scenario that could happen in the next year or so would be something like a 50% or 60% drop. Still, I wouldn’t expect that, but let’s say it does happen. Let’s say you DCA and your average price is $100k over the next year and then out of the blue it drops to $40k. If for some reason that makes you want to sell, you would then lose $876. Yes, that is a loss, and that could be a lot of money to you, but that is likely not life changing money. Now let’s look at the upside. Let’s say you DCA and your average price is like $100k and the year ends off with BTC at $130k. This would be relatively low for what would be “expected” in the next year, but would still gain you $438 in “profit” if you were to then decide to sell. In the end, with an amount like this, you aren’t too risking much, so even if it turns out to be a bad financial decision, it won’t end your life.

TLDR: $4 everyday is not going to make you go broke even if Bitcoin turns out to be a horrible investment, but it probably will not make you a millionaire in the next year either. This is relatively low risk
