Selling BTC for Alt Coins?
If that is done, I think it is possible, but not good for the health of our investment. If it's already in BTC, yes, just totalize it and if you are really interested in buying altcoins as much as possible, use other cash. When we do that treatment and lay, our investments will be sorted and there we can also assess which one we focus more on in the future whether in BTC or Altcoins.
Buying other than BTC is also not a problem and is forbidden, but many remember that we are more careful in choosing because there are quite a lot of shit coins in circulation and have been listed on various exchanges without price movements and there.
