Well it is a good time to trade with other alt coins considering that BTC is on it's way to an all time high. I've already profited from a couple of altcoins the past few weeks and I've purchased a couple more by reading threads here about coins that have potential. I think it's all about making the proper risks on which coin to trade by researching the coin's potential.
yes no doubt that bitcoin is trading in its all time high price, but still the price of bitcoin has still good potential and still it is expecting that the price of bitcoin is increasing more and more therefore trading bitcoin is still worth and can give you good profit, but you just need to trade bitcoin for long term investment and not for short term as the market can possibly take a correction and the price can fell down a little, therefore long term investment will be more profitable as compare to short term investment.
