Bitcoin start to pump since two days back i think, but the altcoins price are getting down.. Time to buy altcoins now.I hope also Ethereum will rise.
Bitcoin are more and more popular. Big investors will not invest into altcoins but in well-estabilished cryptocurency such as Bitcoin.

to invest in bitcoin you need a lot of money to get big profits, and I see big investors also investing in altcoin because investing in altcoin will also get profit, so my conclusion is altcoin is also worth investing in other than bitcoin
