Everyone in this field have Thier own strategy of the trading  .
Here I myself have simple stretagy , but looking much risky for another people , because here in my stretagy I enter in those altcoins which  get down to very low then what we expect , for exmaple , for the digibyte coin we alwere expected for very high price to about 10k Satoshi atleast but since one year we are seeing that price didn't exceede more than 600+ Satoshi , so here a type of fear revolving around our mind that it is getting down and down and Result into risk for the Investment .
But here I seen this is a positive factor , as we know that price got dumped to avoid 80 Satoshi and that was perfect time to buy Instead to get into fear , and also I did the same and bought of about amount 1 btc + and today what I have I can see , today price of one dgb is more than 440satoshi+ .
So here take the entry at the dump and with the use of small understanding I am in big profit .
