So I own $1000 in bitcoin but I want to invest the remaining amount to accumulate a whole bitcoin. The prices fluctuates every second so how can I do this on coinbase? I believe this is called a market buy order and I've looked at the steps on how to do this but I think they're outdated or wrong.
Whats outdated or wrong? Theres no such thing yet price do fluctuates every second and those buy orders youve seen are real time.
Regarding on the question that you do tend to accumulate 1 whole bitcoin then there are lots of ways actually but since you are already on coinbase then you can
also opt in to buy.
