Also, going entirely into altcoins is a bit risky in the sense that your crypto could diminish significantly relative to BTC in a short period of time. Own experience: value of my portfolio in USD increased with roughly 800% in the 1st half of this year, but value in BTC decreased with 20%. A nice profit but could have been larger if I had a significant percentage of BTC in that timespan.
Not trying to be a smart ass, just trying to do math here.
let's say BTC value was $2K when you initially invested, and let's say you invested $20,000 or 10 btc.
So if you made 800% you would have $160K, but your value in BTC decreased 20%, so you have 8 BTC. That would mean BTC would have to be worth $20K each. Slightly confused here.
After much trial and error winning in crypto is all about understanding technical analysis and managing risk. Other than doing tons of research and hastily buying before everyone else when news comes out the charts will usually forecast the movement before the news does. Many of us saw the BTC correction far before all the china news FUD that just made the correction timespan much shorter. You wonder when whales choose to buy and when to sell...TA & market manipulation. Figure out their game and join it. Patience and a solid strategy makes a winner, but it's all about not drowning in the pool. Keep treading.
