New to Crypto, have a few questions

Hi folks,

Just had a few quick questions that I'm still a little unclear on.

Firstly, I noticed that there are the same altcoins but on different exchanges, such as Tronix BTC and Tronix ETH, which seem to be completely separate prices.. Why is this?

Secondly, just to understand how / and how often day trading works with bitcoin, are people trading on 5 min, 15, 30, hr minute intervals?

And are there any really specific metrics or indicators you'd recommend? I'm generally looking at tradingview.com on graphs that track moving average conditionals.

Right now my main strategy is simply investing in up-and-coming altcoins and holding.. I think. Would love any resources people recommend or strategies that have been working for them.

I think once an altcoin doubles my profits I'm going to pull out me initial investments to reinvest elsewhere. Any rules of thumb people follow?

1. Because Bitcoin and Ethereum are different prices.

2. What ever pulls a profit.

3. No.

Wow thanks!
