JSterni, yes i made some good decisions, some bad ones. Most bad was investing in two coins during hype TRON and VIBE, but probably in the end, both coins could be ok, but now mainly TRON sadly looks like scam.
What is strange, and i dont understand why, how whole market is connected. When bitcoin falling, almost all falling, but when you trade pair BTC/any altcoin, selling altcoin when BTC falling dont make sense to me.
Yeah i enter to make some profilt of course, and its not pleasant, when all coins fall for several days.
The best advice is not to follow most of the advices made for instance here in the forum. Use everything as a hint you follow up to do your own research. It is your money, it is your decision in the end. Accumulating information where your investment is based on is no rocket science. There are some critical factors you should review, this will dramatically increase your outcome.
You are right, the whole market is connected and most coins show the same recurring patterns when BTC is moving. In most cases it does not make sense to sell your altcoins when BTC is falling (buy low --> sell high). Either buy "the blood" --> meaning coins dropping harder than the average market drop and gain some profits when markets recover OR hold your bags (especially if you made decisions for longterm coins).
