Are you old enough to have experienced a bear market? Investing 100% in stocks can suffer big drawdowns when there is an extended bear market say down 40% over several years. I would diversify with small portions (5-10% each) in gold, crypto, bonds and cash. If you are dollar cost averaging into stocks it's important to keep investing when stocks are going down. Also assume you own your own home - if not that should be your first priority.
