No. You can't say the same for all crypto. Bitconnect is a PONZI because it is paying the early in investors with money from the late joiners, and when people stop joining it will collapse.

Cryptos are high risk investments, that could go up in value or could go down, and may very well go to $0.

The outcome could be the same for Bitconnect and any other crypto.

BUT THEY ARE NOT THE SAME.

Bitconnect promises returns which are impossible to sustain in the long term and is guaranteed to go to $0 eventually.

Other cryptos could also go to $0, but not because they made promises on returns that were mathematically impossible to sustain.

If you don't understand the difference, I recommend you keep all your money in bitconnect.
