There is no real certainty in the world of cryptocurrencies. The reason is because of excessive market manipulation. Is this a bad thing?
No, if you know how to manage your money you can make a profit. It won't happen overnight, but you can make some profit.
What strategy to follow, if you are new, look at which coins are relatively new, and invest in them. For your profit to be real, part of it must be prior research and a bit of luck. You should know that the coins that are at #1 are not always the best option, get good profits by aiming for those that have a growth between 3% and withdraw when it reaches 10%-15%
If you aspire to more you can leave your money longer with high probabilities of losing.
Don't be afraid of whales.
Whales fulfill the function of accumulating large amounts of money. You can use this to your advantage if you understand that this is a free-for-all. There are no real allies. Withdraw your money when it is most convenient for you.
Be responsible with your profits and losses.
