you tried to explain that Bitcoin is a rather lower risk investment than altcoins, and that is probably the fact, but one should bear in mind that there are different altcoins, and take longer period to draw conclusions
at the moment, Bitcoin is in the best position to grow, since there is a tone of positive news, but if you look at six month chart, most altcoins provided better return compared to Bitcoin, at the moment part of that profit is going back to Bitcoin, and will be back to altcoins after some time and Bitcoin rise in the meantime
of course, one should draw his own conclusions, and do research before investment, this is not a financial advise in any mean
If he can invest bitcoin from a few months ago and still hold it until now, he will make a big profit if he sells right now. With bitcoin price still increase, the risk of losing his money value will reduce, and the profit will become bigger. Some altcoin is also increased, but not many of the altcoin can increase this time because that altcoin needs more time to pull up the price to the high price.
But we will see another rally from bitcoin and altcoin because the price will not just stop at a price now. We can suggest other people, but we can not force them to follow our suggestion because they need to research themselves before they decide.
I think its still better to invest in bitcoin if you want to gain and earn more profit knowing that bitcoin as of the moment are having its slow bull run which I think will continue happening. Also, there are several speculations that it the bullish run of it will continue until third quarter next year which they are expecting to happening due to the trend of bitcoin bull run every 4 years. Altcoins such as ethereum, ripple and elrond on the other hand is I think good to invest with also.
Yes, but if he wants to diversify the investing in crypto, he can invest in altcoin too. The bull run for bitcoin happens again, and I hope that bitcoin price can increase so high and break $14k. Ethereum, Ripple, and other altcoins try to survive and try to rise from the low price to the high price. But still, it needs time to see that will happen.
