Thanks all for your advises.
You have to be calm and make the right decision between buying and selling. You buy extremely high prices but sell at lower prices than the market. Therefore, I advise you not to focus on price increase or decrease. Do not be greedy without loss
The biggest mistake new people make is buying the top and selling lower. You need to buy when prices are red, don't chase the pumps, it might work out for you once or twice but in the long run you will get burnt by doing so. And also spend the time researching coins. The biggest profits are in those coins that most people have never heard about YET.
the only mistake that i see you making is buying altcoins that are already pumped like hell and then complaining about the money you lost after they got dumped.
As mention in the first post, I still have about 900€ I am willing to invest but I have no clue in what. Should I conclude from your responses that I may be too late to order more XRP as the price is now too high and even if I wait a correction or two it will be still a very risky move?
Dude, it's the only beginning. You earn a lot of experience with your mistakes. To make your decisions more deliberate you need to study trading. It's a serious thing that requires a lot of effort. Try to find an experienced and succeed guy who will teach you.
One "experienced" guy at office suggested me IOTA - XLM - BURST - FUN - ADA - TRX, I am not sure if this is the correct move...
Without tactics there is no success buddy, as you said you have to gather all the information about the bitcoin price movement in all the coins chart. You will get the knowledge as time goes from the time you comes to the forum.
There are some chat group are increases in the telegram which is used to learn about the concern investment option for the bitcoin and altcoin investment methods.
Trust me, i know how that feel mate. But we need to fix your strategy first, we not buy more when the coin up ( i mean me, im not buy while its keep growing) we buy when it go down. And also join some telegram or discord group who talk about daily trading, at least youll learn something though and try not to do same mistakes
I joined the XRP discord, it is pretty cahotical there, do you advise a specific one?
