...... Are there chances to see CLAM hit its all time high in BTC pair around 0.0135 BTC in middle of 2015? I did not join crypto in 2015 so I don't know what happened with CLAM within 2015, and why the coin hit such very high price in BTC pair.
Everything is possible in crypto markets.
CLAM is a solid and reliable coin. Price may, of course, goes higher when more people want holding it instead of selling it.
But investment risk is always here. So never invest more than you can afford to lose.
