Hello maybe its kinda noobie question but I also try...Price of omg was around 200k sat then around 160 and I wanted to buy but maybe I should wait a little bit longer, now its 140k and I really want to buy but price of BTC is rising so much that in fiat it does not influence price of omg so much (still around 8 dolls)...so when btc start falling price of alts (neo, omg, lsk) should go up? or it will follow btc trend and also will go lower? Because now people try to put money from alts to btc mainly I guess.
Yes, you might want to go through the charts and see the price level that the coin is usually stable at. Once you find that, then you should invest.
