top 5 altcoins for me are..

Ethereum -of course as the next to bitcoin when Bull comes.

Litecoin- even this currency seems to be fading from being top 3 yet i believe that there is a future for this one in Bull

Ripple- this centralized currency(as what they call) is very promising and have shown how many Pump in past

Neo- a chinese Ethereum that says to be sleeping Dragon.

Binance- the fastest running Exchange and coins as well.
