But I feel like if I trade bitcoins I might be able to make a profit. First I am going to start this business with a small amount of money. If I can make a profit by trading then I will trade with more money later.
Not to be pessimistic here, but what you feel is subjective. You could also lose when you trade bitcoin. Some loses a lot during the bull market thinking that it will go beyond 100k to 200k in value but instead did a major pullback and now coming back again. Yes do a business and only trade if you already gain the knowledge on how to do it. Its not a joke to do heavy trading especially in crypto that is so volatile.
