+#### Why using SSL insecured mode now
+
+This so-called **"insecured mode"** 
+
+1. permits you to actually connect to a **TLS server** (port 443,9443, etc., especially with expired CA Certs such as **Blynk Cloud**). It won't let you connect to plain non-SSL server because full encryption is still required.
+2. You never have to worry about CA Certs' update and to include every trusted CA root certificate of every TLS server
+3. Still requires **encryption**. It just does not **validate the certificate or fingerprint**. Insecure because we could be subject to a **MITM** (**M**an-**I**n-**T**he-**M**iddle) attack.
+4. It's still much better than **plain non-SSL** mode which just communicates using no encryption at all.
+
+So this is the much better choice.
