Yeah Altcoins has huge potentials really I am personally into Altcoins right now because I can buy some of them with my smaller funds but my plan is that all my profits in Altcoins will surely be converted to Bitcoin. I can't buy some Bitcoins with my small fiat money but I can do that on Altcoins I am into quantity right now because I can't do that with Bitcoin.
The strategy you use is actually not bad if in the end you convert the profits you get to Bitcoin because on the one hand you still quite like Bitcoin even though you are hindered by the amount of money you have when you want to buy Bitcoin. However, for me this is not an excuse because Bitcoin can also be bought with small amounts of money, but with this kind of strategy it is also quite good as long as you don't keep altcoins for a long time. Or do you just use altcoins as a stepping stone to be able to buy Bitcoin through the profits you get from altcoins.
