This might not last long during new year there is going to be a huge dump and by huge i mean really huge. Alts will crash as usual but there are sources claiming the btc will fall back to $10k. Obviously it won't stay till that price and will get pumped quickly but still it's a point to note.

The current situation is really favourable situation for all the coins. It's better to put stop loss if you have any major holdings no one needs to have a sad moment on new year.
