Thank you for creating this thread.
Investing is crypto was crucial in 2010 and it is important now in 2024 also. Some investors saw far into the future and invested significant amounts in BTC and ETH and they are reaping the benefits today.
However the next best time to invest in BTC is now! The crypto market is full of coins and tokens making a beginner overwhelmed.
My simple advise is to DYOR and always stick major coins/tokens that have strong fundamentals and strong teams. Meme tokens are short term, I do not see any future in them except for doge which has a celebrity associated with it.

The best investment technique is to DCA. That has been the best strategy by far for BTC.
If you have good trading skills and can time the market, buying/selling a few coins could be a good idea. But never be too greedy. A goose in hand is better than two in the bush.
Lastly, not your keys, not your crypto. Invest in a good cold storage wallet and stay safe.
Cheers.
