If your focus is on discussing trading, I think this thread should be moved to the
Trading Discussion board.
2. Don't Buy at the Peak, Buy during a crash like now, so you can Sell at the Peak like $70,000.
Do you mean buying at the peak is buying in a green market?
I think a trader can be more flexible than an investor. Daily trade or scalping, can buy at each market trend (red & green). If your target is just a small profit and for a short-term trading goal, there is nothing wrong to buy at a green market. Except if you buy for holding a long term, better to buy in a bearish (crash/drop). But it isn't for trading purposes, it is for investment.
3. Don't borrow money to invest in crypto, ~
Sure, borrowing money for a crypto investment is a bad idea, especially if you are a newbie.
Investing in crypto coins is high-risk, it will be riskier when we invest with loan money.
7. Remember to use StopLoss especially when in profits and trade wisely.
Using Stoploss isn't a must. If you trade daily and find you have got enough profits, kindly sell your coins. No need to use stoploss feature.
