Yes we do. Altcoin is an alternative cryptocurrency (to Bitcoin), and each alt offers its possibilities. Many altcoins are safer than BTC and their transactions are faster. They are more anonymous and you can use these coins for different purposes: for ICOs, buying/selling stuff in internet, even paying in restaurant!
I think altcoin is a very profitable investment, but we must be careful in choosing it. Altcoin can be very profitable in a short time because there are many altcoins that suddenly get a pump. therefore we must be able to capture the signal or analyze it correctly. but if you talk about security, I think Bitcoin is still the safest if it's for long-term investment. so the conclusion is that Altcoin is very good for trading and Bitcoin is perfect for long-term investments.
