Coins with the coin itself having purpose or function are great. I like finding ridiculously low marketcap coins that are having great community growth and supposedly new tech releases coming out like CSTL or XTL. It's the hidden coins that are hard to find that can really yield the best profit results.
CSTL has a wide spread and an illiquid market. Easy to trade/flip for profit while building up a supply. Masternodes and an airdrop platform are being released.
XTL is just a crazy low satoshi coin that you can put in a low bid order in and then flip.
Both are great, can do right now for profit, kind of coins.
If interested to review:

https://stocks.exchange/trade/CSTL/BTCthat is a good thing to know before applying for airdrop, because it can turn your wallet to spreadsheet without adding values or towards it. i prefer doing work than airdrop token. because many does not have values to sell, even no exchange listed on token.
Airdrops are good free money but not all are worth to join and to hold. I find day trading as a bad habit of trading in my experience but I know there are traders there are that earning more than enough.
The best way of making profit is through investment or trading on crypto-currency, and make profit from it by buying a high quantity of favorite token and resell in a short period of time and make profit.
