In my opinion this is a trading technique because the market is in a positive condition, buying at a price lower than the purchase price by targeting prices to make a profit. So the basic idea is to buy low and sell high but altcoin rates will be adjusted to the level of Bitcoin we use .
That is of course a simple logic and one does not need a high mathematical skills or technical analysis to do it. You just have to invest it your money in a point in time when the price of the coins you want to invest in is down. If we take a clear observation of the market right now, the values of most of the good coins is down. This is not the failure of the cryptocurrency nor stagnation but the recession phase and there are good signs we will recover again so it is high time to invest in cryptocurrency now.
It is all about money but it need a perfect planning as well, buy some coin if you have money being late is not good at all, even if you have small amount of money try to buy some coin, it will give you profit, crypto currency is all about selling high and buying low so it is good time to buy because price is not too high so better to buy some coin and hold for long term, it is totally full of profit.
