I have no tactics , I just wait until the market starts to recover and the price will come to the same level
The worst thing you can do is wait until the price comes back to the initial state, sometimes you can wait a dozen months and a good investor in such a case is cheaper to average the purchase price and then there is a profit when it grows.
Waiting is very effective, therefore, you have to make sure that you are investing a money that is intended for long term so you'll not worry.
Everyone has our own tactics but we should stick to those what we believe because we did a research and analyze it carefully and not because of other people's call.
