If I wanted to buy $1,400 of bitcoin every week, should I buy $200 a day or should I buy the $1,400 every week?
Any options will be greatly appreciated.
Each decision will have its positive and negative side.
All in weekly with $1,400: You will save some dollars to pay a fee of trading (purchasing). And if you withdraw it to your personal hardware wallet directly, it will also save dollars for fees of withdrawing.
But, you may miss some chances to get the lower price if once the price drops after you are all in buying BTC at that time.
Daily on $200, it may lead you to get lower price following the daily changing price. You may get it lower or even higher.
However, once more, the fee to spend maybe much more because you need to buy it several times.
Or, you can buy it twice, by dividing twice purchase in a week to save more dollars for fees but also get lower price probabilities.
