I agree. I also actually do the same, since it's more economic and cost effective to buy those cheap coins that even goes a little down during dips; I think that many people in the crytpcurrency market, especially those engaged in trading, do that because its a good way of expanding their portfolios while avoiding to burn their pockets or stashes of coins. As most say, in this market, diversity is key, so if you really want to load up your holdings without breaking bank its best to time your purchase when the asset is low in value.
