I choose to invest my money than to save it, in that case my money will be increasing.
Yes, investing gives good returns but it should not be taken for granted. Investing money has a risk of losing the part or the whole capital whereas saving can assure you the safety in quantity and rise or fall in the value in it. Since currencies like bitcoin is highly volatile, there is a risk even if the funds are kept ideal so taking it to a step ahead and investing it is a good idea.
Right, I would prefer to inves it rather than to save it. Yes your right investment has a risk to lose all of your capital but you need to take it if you want to make a profit. Every transaction you have made has a risk even storing it in your wallet.
Saving it is also good in terms of when you need a money to spend you can use it and storing it has a possibility to become doubled since bitcoin is still rising.
One end up with the same level of risk if he has invested in any uncertain option of investment like bitcoin. I do have my cold storage but still, I don't keep my all funds there and rest of it is invested in various investment options some with less risk and some with high-risk scale. I am quoting mark's statement here,
