There is no need to switch totally to ETFs. You can keep your stocks and add other ETFs like SPY or SCHD to your portfolio, as they provide more stability and broader exposure to you. My suggestion for you is to just maintain your core stocks and invest in ETFs for better diversification and for steady returns.

In the States, cryptocurrencies are considered taxed property. This means you must pay taxes on any profits you make from selling or trading bitcoin. There is no tax on just moving money from an exchange to your bank account; taxes apply to any earnings from trading or selling. You must maintain a record of your transactions for your tax returns, allowing you to track any gains or losses.
