Just my thoughts : Bitcoin...the grand daddy, with high value, but unfortunately a lesser and lesser revenue stream. Low turnover, so to speak.
Litecoin...the altcoin to watch and invest in RIGHT NOW. Much lower value, but high turnover. Turnover is key.
Dogecoin...????????????? No idea ! But I have some and I want to give them away. No, really...I'm serious ! Reply with a Doge address and I'll send you some Doge. Let's make it 100 Doge for now. And please people : I'll be sending this present to the first person replying / voting ONLY.
Kind Regards
