It seems to me that the best strategy now is to do nothing and wait. Those who hope to invest in cryptocurrencies should keep their Fiat because there is a possibility that prices will decline further. Those who have coins already missed the moment when it was necessary to sell. Now we need to reduce the number of proposals and due to this the price will go up. Whales will not miss the chance to sell coins much more expensive than they bought and will shake the situation.
The truth is hard sometimes but I am 100% with you, the people who are still invested largely and have no FIAT let to get in now have missed the train to sell. But it's all a learning curve, next time a lot less people will be falling in that trap and secure their profits while they can. Making a mistake once is a chance of learning, making it twice is a sign of resistance toward learning
