As far as I'm concerned, you can avoid risks only if you hold.
Even that is no guarantee! Long term you will lose if no person will buy crypto, because there is a new product at the market or there is a crisis in the economy.
There are many ways to get nice profits short time for example this:

That is right. The risk can be minimized easily by making the first move a wise move. It is planning your investment duration that is the term of investment. The second is choosing a good coin in the market that can easily give you some good return upon the rise in the values of that coin.
This way the loss is minimized to a great extent. The rest is the market uncertainty in the rise or fall in price which can also be taken care of if you hold the coins and not sell in the down market. So eventually you will be able to earn big without loosing any and yes you can earn big without loosing.
