Now my question is, is it good for my future that I have sold my altcoins and invested in bitcoins?
Taking profits in the Alt coin market is not a bad idea and like you I also like to add any profits to my bitcoin holding. For me the main investment is still bitcoin and I evaluate any other crypto currencies in relation to the change of the bitcoin price. In my opinion alt coins are more risky than bitcoins and should therefore offer us a higher return. To avoid bigger losses it's good to take profits and grow our bitcoin investment. Why not use any new money that you want to invest in cryptos to buy new altcoins? Like that you can rebuild a diversified portfolio while having the majority of your money in bitcoins. The halving next year in bitcoins is going to bring new positive incentives and should push the price higher. As long as you are not switching back to fiat money you are doing nothing wrong.
Initially, altcoins were bought for some purpose and for some reason, it is obvious that the OP saw a perspective in them. It is difficult to say at the moment whether this decision is correct, since some altcoins are indeed able to show significantly higher growth than bitcoin. Yes, he can buy altcoins again with free money, but if the OP has now decided in favor of bitcoin, then it seems that the strategy will be to buy bitcoin.
Decisions made whether right or wrong because it would really be only known if they would neither able to make profit or losses and this is why its not really that something that right if we do make out judgment on
whatever other people been doing on their decisions on their investment.If they have decided on touching altcoins to accumulate Bitcoin on selling out those coins then its not a bad idea on which we cant really be able to blame out people on doing such thing because nothing beats out Bitcoin when it comes to potential but there are some top altcoins which are that worth on investing into. This is why decisions made will
completely be random on each person because some would be sticking on alts and forgetting bitcoin and some would really be just focusing on Bitcoin alone and dont tend to touch up
altcoins because they arent really that confident on doing so.
