if I think you see the price of bitcoin and altcoin now starting to rise, so I believe it's also the best time to buy bitcoin and altcoins, because now the price is still low, so I'm sure you will get more profits.

As soon as the project is listed on the stock exchange, all participants of the bauti begin to sell and the price falls. All who bought with a bonus also sell and the price drops. People give in to panic and also start selling and the price drops even more. Here you need to buy)))

today many coins go down and almost all coins go down so now is the right time to buy as much as possible. when Bullrun comes you will get a big advantage from some potential Altcoin. for this year it's difficult for Bullrun, maybe just a few percent and not as high as he has ever achieved.
Choose coins that are good and have great abilities so they can grow and can increase their value.

Its better to buy on ICO stage because the price of the altcoins are in dip price and you can sell first to high price if the project have a exchange already. But it was to risky to buy some altcoins if we don't know on what happen in the future of it.

I think right now is the right time to buy altcoin, because now the price is still low, because seeing the development of altcoin prices is also getting better.

It can be very reasonable to invest in altcoin in periods of stability after the rise of Bitcoin. Because when they are rising or falling, all the alts are almost down.

With the present state of the market, I think the best time to buy is when the project hit exchange or when the coin is in the dip.

I think you need to first analyze the project and only after that decide when to buy coins: during ICO, on the exchange, or when the price fails.

The best time to buy altcoin and maximise profit effectively is durring dip. Buying altcoin at dip price puts you in a good position. To easliy make profit when there is a small spike in price

Now ICO stage buying is very risky due to Scammer come to crypto world. So i think good stage is in exchange duration. Because lot of cryptocurrency price was dip after come to exchange. Some coin prices are lowest more than ICO and Presale prices.
