Of course there are always risks both in holding or trading, but in my point of view, holding poses lower risks and if you hold a handfull of coins, chance is that at least one or two will increase their value many times with time, and this will probably turn out to be more profitable than doing trading for quick cash...
The risk is that some of the coins being held loose their value completely, but in crypto pacience is the key and high rewards come to pacient holders ...

Never forget that nothing can go up forever... and what goes up, will also have to go down...
