If you have a low risk tolerance and want to prevent volatility, the way to go will be to invest.
When you just want to hold and play safe and you don't want to deal with the volatility then investment is a good option for you.
If you don't have the guts to make yourself become adaptive in the market then it is much better for you to hold until it is profitable enough for you.
But trading could be appealing if you're more of a risk taker and would like the opportunity to earn big returns quickly. It is essential to understand that trading and investing need not necessarily be mutually exclusive.
But there are also people who become successful in trading because they grabbed the opportunity to trade as soon as they can and make their asset grow more.
At the end of the day, it is still your own decision on what are you going to prioritize to help yourself grow your money.
