Bitcoin has proven to be able to provide many benefits to many people. Bitcoin has even created a lot of new rich people in a pandemic situation, this makes Bitcoin more popular and gain the trust of many people.
Still, I do see veterans are not recommending to go all-in into bitcoin investments as bitcoin is an experimental project hence investing only affordable is highly recommended. I agree that bitcoin has proved its potential so far in more than 11 years of time but anything could happen in future hence we should not risk our life with only one investment opportunity which could be bitcoin or anything else.
Bitcoin really got the highest level of trust but that does not mean we can invest all our money into it. Even Bitcoin is highly reliable one, we should diversify our investments along with other investment opportunities like stocks and gold to balance our life at any unexpected events.
We don't know what the future will bring to us, this is why, you always need to have contingencies and not go all in. What if in the future there will be new technology that will be deployed and bitcoin will become obsolete? Who knows, right? So if you want to take care of your investments, don't forget that you are holding some stash and be updated with the market. So if anything big is about to happen, you are well-prepared. And right now, bitcoin is still the leading cryptocurrency among thousands of these alts. And I believe, it will stay this way for the succeeding years to come.
