Thanks for the warning, but look like past few week bitcoin price rally don't affect altcoin price at all, most of the altcoin price don't have big movement, but just be careful some useless coins will pump by some group, new investor should doing research before investing.
Should take a look at past graphs, first pump bitcoin and altcoins after. People begin to diversify their investments, and buy altcoins for bitcoin. Still got a buddy up ahead.
