If you have decided to buy altcoins at the current price, you should be prepared for the fact that the price will continue to decline and you will hold a losing position. And in the case of a continued decline in the price, you should have enough stablecoins left to get a good average position by buying altcoins at a low price.
That's what everyone in this thread is thinking. But the market has taste for doing the opposition when everyone is so sure about it. I think we've at nearly the bottom, even if it falls, the overall trend will be bound back.
As always, nothing is certain in the market, if you think it is going up it will go down, if you think it is going down it will go up. There is no method that tells us where the bottom of a coin is, so if you are a long term investor you should wait to buy at a heavily discounted price and should use the average price per coin. This is the best strategy that will help you never to miss any bearish opportunity instead of waiting for a final bottom that we cannot identify.
