Your strategy is complicated. My suggestion is to stick to a simple strategy: buy bitcoins and hold them for the long term.
This is the safest way(holding BTC) at least but the least profitable route along the span of time. Taking advantage of the altcoin surge brings more profit than holding Bitcoin in a long term. Diversify and never stop trading to maximize the potential profit. Investing only in Bitcoin and holding it for a long time means you are sleeping your coins while waiting for the possible profit of BTC to doubles or triples its value in the future. But investing it on different altcoins (as long as you don't get busted) can give you a possible profit of more than 100x the profit you take on just holding BTC.
