Exactly. All of this could only mean to follow certain rules in order to make a good investment. Speaking of which, I have compiled a simple list which tells the basics of investing into Bitcoins or any other alt coin.
They are as follow:
1. Buy Low (preferably in small chunks)
2. Sell High
3. Diversify your investments into other alt coins (not putting all your money into Bitcoin)
4. Sell some of your BTC into Gold.
5. Take 10% of your profits into savings
6. Invest in a PoS coin with a high interest (stake) rate like Diamond. (25% APR)
7. Never invest what you can't afford to lose.
If you follow the above rules, you will do fine and make decent profits (apart from making a smart investment)
Just my opinion.
You will never know what is the output if you will not put yourself in an actual situation. Also if you want follow any ways stated here, you can come up with a quite accurate answer by yourself.
Just remember to take your investment strategy seriously.
