if you put it in an exchange that has a good reputation and is guaranteed I think it is a very good idea, because a lot of people are doing that for now, meaning the profits are not only from trading but also from staking for the time frame you have specify.
Nothing is guaranteed on any exchange but chances are very low that exchanges such as Binance, Kraken or Coinbase would become scam. I love staking as it is "easy money" but I also always take my profits as anything can happen in crypto.
If you want to stake then you need to do some work for this also because it's good and can give you very good profit but if you are not in trading, and you are going to hold these coins for long time before staking you must look into project and team because this is very important.
After this there are many types of staking you also need to check this as well because few projects giving other tokens instead of their own and few are POS which will give you reward for helping blockchain. I believe in this rule that not your keys not your coins so try to have very solid platform for staking if you're not able to have your own wallet for this.
