Bootstrapping vs Fundraising

I think there is no preference and it highly depends on the business model and the real potential of that as well as the financial situation of founders. Of course, bootstrapping with the capital equal to an expected investment is the best as it increases the potential for larger investments in the next rounds and founders keep all the equities; but talking about startups, most founders don't have the required capital to do this. I think a combination of both doesn't slow down the growth because of relying on the small amount of capital provided from bootstrapping and keeps the larger portion of equity (so the decision-making power) is ideal.
