Nothing is 100% guaranteed hen it comes to investment. Either online or physical invest, you should put in mind that it may fail, just that investing in BTC comes with a very low risk. If you have invested all capital in BTC, what happens in case of emergency? You will have to sell some portion of your investment for money. What if the emergency comes during bear when there is a great dip? That means you have no choice than to sell at lost. It's a good idea to have some investment in BTC but one should still keep some cash in bank in case of emergency.
