People have been comparing Bitcoin to tulip mania for years, since it started. It's not the same thing, they're two completely different items. Give it up.
yeah, its not new to see this kind of news. all big influencial people are keeps saying bitcoin was a bubble, tulips, ponzi or etc.. but why bitcoin still here? standing strong and keeps on moving to reach again is new all time high. more people are still believing on bitcoins and most of them are risking anything just to join this bitcoin roller coaster ride, therefore they dont really care if what will be the future holds on bitcoin.
