In my opinion, As of now it is not advisable to invest your or our bitcoins because IMO it is better if we just keep it safe in our bitcoin wallets rather than taking risk on investments that may turn to scam or get negative profit.
It is good that nowadays we keep our bitcoins untouched as the price of bitcoin is increase every day and it will increase more higher in the coming year so that will be a better profit for us that we keep our money in bitcoin and find it with more higher value.
