the title says it all, i wanted to learn some advice from you guys, how you guys actually manage trading if you already had with that such amounts or more
definitely not. going all-in on any altcoin is mismanaging risk. it's "putting all your eggs in one basket" so to speak, in the context of high risk and highly speculative assets. so the smartest thing to do is spread around that risk and diversify. i'd rather put 0.1 BTC into 10 different coins (or maybe into 5 coins, with amounts weighted based on my view of their fundamentals and speculative value).
as it is, i'm actively invested in about a dozen coins, most of them for the long term (> one year, due to capital gains taxes).
