Hi there Luc,
First of all I'm new here and I would like to thank you for sharing so much valuable information about trading cryptocurrencies. Especially for new traders like me.

Just a quick question if I may:

I was wondering on what point are you trading your bitcoins/altcoins back to dollars? Is it on a daily basis, weekly, or? Because every altcoin is connected to the value of the bitcoin, or ethereum, whats the best moment to take your profit into dollars? The next day your profit could be vanished because of a dump of the bitcoin value, right?

I hope my question makes sense, and would love to hear about your methods! Thanks mate!
