I agree with many in this forum. Don't trust what other say in these forums. They are a great place to explore and learn about cryptocurrencies, but what works for one may not work for you.

The day trading you are looking to do is very hard. If you are not experienced, you will lose your money. If it were me starting again with my new knowledge, I would place all my money in a stable coin. BTC or ETH might be good, except, we are not 100% that it will not fall back down. If you see that happening, and you invested, do not panic and sell your coin. If ETH and BTC fall, most of the other coins will too. Again, if they do, and your starting to take a loss, don't sell.

Once in on a stable top 100 coin, take a small percentage, like 5-15% and pick another coin that looks like a bigger gamble, but is gaining. Trade on that coin for practice. Record your trades, and at the end of each day or week, see if your making more money than if you left it in the stable coin. Always remember, you will not win everytime. Do not let it get you down when you lose on a trade. It emotionally impacts you more on your losses.

When you are confident you can beat BTC or ETH gains, or are taking less losses, then you are ready to go big!  

Good luck.
