You should start with the fact that any investment poses risks, even Bitcoin does. One should be aware of that and especially in Beginners area this must be said over and over again.
_ Even though am a big fan of Bitcoin, it wouldn't make you filthy rich, unless you have a large capital, the real money is in the Alt where the high risk are, just pick the right one.
Actually altcoin investments are a couple of levels of magnitude riskier than Bitcoin investments. And this means that if one has chosen the wrong altcoin or the wrong moments to buy and sell, ... he/she can get burned (too) easy.
In my (quite long) experience all the altcoins I've tried out sooner or later went down and never came back to their ath (against Bitcoin, I mean).
_ Be patient because that is the key.
Yep. Patience in buying and selling, patience in learning too!
_ Control your risk; people mostly waste their money gambling on trades that gives only 1:1 reward ratio without remember every $1 you waste could be $100 during the bull run or a year time.
1$ lost while learning is still better than 10k lost because one thought he understood trading (and trading is very difficult for most, actually).
So there's no universal truth; one needs to learn, one needs to understand whether trading is a better choice, or investing, or neither (!).
_ Learn to sell: you need to learn to cut your loss, even though you are -70% , the left over 30% is reinvested than slowly grinding down to -99% because you are too stubborn to admit you are wrong.
Yep, most traders lose the big money because they either became too greedy, either didn't know how to cut the loses.
_Dont give up: in crypto you will make bad investment, sometimes you will just be unlucky, just do not give up.
So true. Trying multiple times, cutting loses, re-investing basically only the gains, repeating this.. it's a good strategy.
_ Take profit: if you don't take profit how can you be profitable? Don't be greedy, just take profit.
That's correct. The only thing to add is that while a trader may want to take profit faster and more often, an investor may even want to wait for years.
But eventually taking profit is the right thing to do; bringing your coins to the grave without having a little fun in life when you were on profit ... would be sad.
All in all you gave more good advises than bad ones, still, it would be great if you would nuance everything in the way you give only good ones.
Keep in mind that bull runs come and go; the advises may be more important when the price is not going only upwards.
