Definitely take some profits. How much depends on the percentage seeing as how 40-200 is quite a big range Perhaps set that aside to reinvest on a pullback or either re-invest that into another opportunity.

Graphically it looks pretty good, but from a UX perspective I feel it could definitely need some more work.

Binance, by far. The only thing I don't really like about is their charting, but I have a TradingView tab running at all times to handle that.

I'd personally go for neither

For the short term I trust it. But all my trades are tightly stop-lossed just in case...

Some airdrops can be worth it. I did a REBL airdrop for 2000 REBL that were worth $ 200 at some point. But these results are far from the norm...

I'm most bullish on Ethereum out of these 3. I only use Ripple to gain some easy profits since it'll probably go up and down massively anyway. Litecoin I don't really have any interest in.
