I started with 5-7k. I primarily hold, sell when the price is high and then buy the dip.

I once made 30k from 400$. It's ridiculous. I bought 400$ worth of BTC a year or two ago. BTC price went up. At that point I had ~3000$. I sold BTC and bought IOTA. IOTA was pumped, I sold it for $10,000. I went all in and bought Ripple at 0.94$. They pumped the price, I was able to sell at 3$, making a whopping $30k+.

Wow. With that track record you should play the lottery.
