I see the opportunity to buy btc and hold it as being a good opportunity, if you are willing to save your coins for at least one year.
There are other investments such as altcoins and icos. It's rare to find a profitable one, but it's worth keeping an eye out.
yes i am also agree with you i think there is no need to invest money in any where else, you just need to hold bitcoin for some time as people are expecting that the price of bitcoin can reach to all time high price in next few months, therefore we should not lose the opportunity and should only hold bitcoin for the price increase.
