Well it's normal to sell your coins in bullish markets because what the essence of you investing if it's not for profits sake? But some people may actually keep their coins even when in profits, it actually depends on your choices and how much believe you have for such projects.

I cleanly favor trading altcoins instead. However, you may divide your investment. embrace other percentage in bitcoin, a small amount of other percentage in ether, and crack the remnants on the altcoins you believe you know how to rely on their impending potential.

I personally don't look at any whitepaper, I just goto Google to type about the best projects to invest in, most people don't look out for ICO whitepaper, just know that.

Depends on the individual, but my advice to you is that, don't sell any tokens anyhow because of the current situation of the market.. Chill till probably by December
