Investing on Bitcoin is the best think to do if you cant decide on what else to buy. I think bitcoin will be trillion dollars market cap in less than a decade. Any opinion?

I cannot be sure about your prediction in market cap. What I know is that bitcoin is the best investment in terms of cryptocurrencies. That is right, if you cannot find a good coin or the best coin to invest in, Bitcoin is always there. There is less risk in investing with Bitcoin because the world has been following it closely enough and rich investors are even on it.
