The most stable way to increase returns is to gradually buy Bitcoin between 6/25 and 7/15.
Then use 40% of your position to open a coin-based grid long.
Use 60% of your Bitcoin for staking and lending with 10% to 20% of the total cost,
and use it all to buy altcoins.
If a black swan event occurs, Bitcoin's initial rebound will be much greater than that of altcoins.
This way, you won't miss out on Bitcoin's gains and will still have funds to purchase some altcoins.
So let's assume you have 1 million.
Spend 1 million to buy BTC, use 40% to open a coin-based grid,
use 600,000 BTC for lending 100,000 or 200,000 position,
and use it to buy the altcoins you want.
Currently, I have set a trigger for a BTC-based grid at 92,000.
